This is related to a question I wanted to poll the list with. How does
everybody here use Gentoo? For personal use? Production use? For
server, desktop or embedded roles? What's your most interesting setup
or use case?

I had Gentoo on both my desktop and HTPC, but I had to cannibalize the
HTPC for parts, so now it's just on my primary desktop box.

Desktop here.  Though I do have one box that could be considered a 
server of sorts since it has no mouse/keyboard and no monitor either.  
Well, most servers don't have those.  ;-)

You really need a website that has this question and just post a linky 
here and on the forums.  Even then tho, you won't get all Gentoo users.  
Only the chatterboxes will reply here too.  lol  Mostly anyway.

That is indeed cool. And a welcome news for me who's trying to
champion Gentoo in my company which, as it happens, is a
stockbrokerage house. One of my country's largest, even :)

Re: [gentoo-user] OT: but cool - NASDAQ is gentoo powered

[Pandu Poluan]

To answer your survey:

All my gentoo VMs are in production as servers. Non-glorious but
essential ones such as mail servers, DNS servers, proxy servers, and
also a couple of firewalls.

I'm currently in the process of phasing out Ubuntu servers from my
company, leaving just one for running Axigen.

I personally don't think Gentoo is suitable for the (l)users in my
company; there's just too much 'moving parts' that will make support's
life a hellish experience.

Currently I am planning to explore (along with Joost and hopefully
someone from the Xen herd will hear and help) a Gentoo-based Xen
Platform. An ideal match, if you ask me, since (theoretically) nothing
can come close to the performance of a Gentoo Dom0.

I use it for my laptop, desktop/HTPC. firewall/router, distfiles
server and NFS boot server. The distfiles and NFS boot servers are
actually VMs due to having to downsize PC space on my desk. (my wife
had a fit about 6 PCs on my desk running constantly.)

Here I have it on my laptop, desktop, build server, build binary packages
server, web server, backup servers, file servers and (hopefully) a media

1 Desktop
1 Netbook (For holiday and during travel)
1 home server (running Xen with virtualized Gentoo instances)

Server provides DNS, DHCP, Proxy, website, email and groupware (calendar, 
addressbook) services.

I had a HTPC as well, but I discommissioned it as it was too noisy. Might 
build a new one at a later point, but for now the WD TV-Live I've got does 
what I want it to do.

Currently planned:
1 more desktop
1 additional server for testing purposes / backup of primary server

The desktop will likely have to wait till next year at this point.

I use it on all of my hardware (except the smartphone)... 

That includes my server (Xeon, 64bit, nginx, mariadb, mongodb, postfix, ...), 
my pc at home (Core2, 64Bit, kde 4.7), the netbook (32bit, atom, kde 4.7), my

All my personal machines have run gentoo for 6 or more years now plus 
my dev VMs. At work, it's encouraged for the dev environments too.

I was interested to read that NASDAQ runs a "modified" Gentoo and 
wondered "what does an unmodified stock Gentoo look like". Then I 
realised I was being silly, there's no such thing :-)

Wouldn't that be what someone ends with after following the install guide?

Well I'm being tongue-in-cheek :-)

We all modify Gentoo to our own tastes, some a little some a lot.

So was I, how much use is a stage3 install?

> We all modify Gentoo to our own tastes, some a little some a lot.

I tend to change what I want changing, not sure if that is classed as a little 
or a lot. I think I'd be somewhere in the middle of those 2 extremes ;)

I use it on my desktops (currently 3 machines, varying over time), my laptop 
and in my (home-)studio as DAW.
Last one is probably my most interesting setup, but even this one is not 
interesting at all :)

I have laptops, desktops, and servers.  The servers are nameservers,
mail servers, web servers, file servers, and SPAM filtering servers.

I also use Gentoo in VMs for network testing at work and have turned my
boss onto Gentoo as well.

I use gentoo on my laptop (1.6 GHz core2duo, 4GB RAM), desktop (3 GHz
QX9650, 8GB RAM), home file server (2.5GHz core2duo), htpc (another
core2duo and 2GB RAM), and various servers (one's a dual P3 1.1GHz box
that's getting retired) at work, both production and testing. Actually,
I'll be moving the servers at work onto ESXi soon.

They've all served me well.

Gentoo at home as my only OS since 2003. Previously I used DOS in the
80's and OS/2 in the 90's, with a little Slackware dual-booting as my
first taste of Linux in the olden-days. I use it at home for
web/email/programming/gaming/photo and video editing/media server/etc.

Gentoo on my laptop since 2004. My first amd64 install, and my first
(and last) experience with ati-drivers. :)

A few months ago I set up a virtual Gentoo server (at vr.org) which
hosts my DNS server, email, http server, etc. So far that has been
working great and I'm learning a lot. I'm going to migrate my domains
to it from other hosting providers. I must establish a proper backup
routine before I do that, though.

I have 1 server running Gentoo for about 4 years, 2 workstations and 2 more
machines performing different tasks.
All this machines at work. At home I haven't changed to Linux yet... Don't
think I'll ever will, too many variables (like the fiance, for instance).

The most intersting case was an old Pentium 100 MHz, 48MB of RAM that was
running Gentoo for about 2 years at work before retiring, serving HTTP, FTP,
MySQL, PHP and a long uptime. Took me a while to install (lets say a month)
cause of the long compile times and some tech difficulties (like for
instance booting an LiveCD from such an old machine). It was fun.

I also had Gentoo for an year in my old netbook (Asus EEE 900).

I have one laptop, three desktops (two at my university), one HTPC
(with an ION Zotac mobo), and 2 servers, for very different purposes
each. The servers are in production.

Some years ago I administered the desktop machines in my work: Ten
gentoo boxen compiling in parallel with distcc; that was awesome.

My most interesting setup by far is the HTPC, I guess: it boots really
quickly (thanks to systemd), and it has a lot of little modifications
so I don't need to ssh into it to do anything: Everything is done
through the remote control.

In all my computers (i.e., not the two desktops at uni, since they are
not "mine") I use systemd (which thankfully has entered the portage
tree), and in my desktop and laptop I use GNOME 3 from the GNOME
overlay. It all works basically flawless.

- my notebook
- my dad's netbook (8 GB disk + 512 MB RAM, minimal KDE still works with
<=250MB RAM usage)
- my dad's PC
- a virtual private server. Primarily acts as an OpenVPN server
connecting the machines listed above. Also runs a bug tracker (Redmine)
and a Hudson build server.

I'm currently planning to get some experience in setting up minimal
appliance-like servers based on Gentoo.

systemd sounds like a nice-to-have project for me.

Which howto did you follow, what do you recommend me to read to start

I became afraid after reading this wiki page, especially the part
about removing openrc and making your own init.d and conf.d entries:

http://en.gentoo-wiki.com/wiki/Systemd

I read through parts of http://0pointer.de/blog/projects/systemd.html
now ... (coming from your mentioned url)

Yeah, sounds scary.

I might play with this inside a VM some rainy day ... using
suspend-to-ram and SSDs both in thinkpad and desktop, so boot-times are
OK and not a problem.

So this doesn't really motivate me to take these risks ;-)

It certainly was for me.

I think it mostly works out-of-the-box right now, you unmask whatever
needs unmasking and keyword whatever needs keywording, emerge it, and
put init=/bin/systemd in grub or lilo and that's it. I *think*, I
could be wrong. I think Michał (Górny) did a good job keeping the
introduction of systemd into the portage tree as uninrusive as
possible, so you can go back to OpenRC whenever you want.

I don't know about the wiki (I didn't use it to install systemd), and
as I said, I think it works out-of-the-box now, and you can safely go
back to OpenRC if you want to.

The boot-times are a nice consequence of systemd, but certainly not
the only reason to use it. I've been using it for several months, and
IMHO it's far superior than OpenRC, which anyways is a fine init
system.

But of course, if you're happy with OpenRC and nothing interest you
from systemd, there is no reason to change. For me, the boot-times and
the fact that most of the services I use have a .service unit file
written by the authors of the package in question is enough for me.

My usecases for Gentoo are desktop / laptop, fileserver, router, a kvm

So i am running Gentoo on 6 of my 7 systems plus the kvm guest.

Since you ask: my workstation runs Gentoo. My old workstation sometimes 
does; at other times it's experimenting with other distributions.

I have a midget server on the LAN (Atom N270) which runs Gentoo, but it's 
too underpowered to do all the compiling itself, so it NFS-exports its 
packages directory to my workstation, where I have a 32-bit chroot set up as 
an image of the Atom. Emerging is done here, making the packages available 
for installation on the Atom. This is a cumbersome operation though.

The Atom serves web, time, squid proxy, dns, cups and mysql to the LAN. It 
runs http-replicator and rsyncd to keep a local portage tree for the other 
boxes. I'd like it to serve mail too, but I've never managed to set that up.

My laptop runs Gentoo, Fedora or WinXP.

I seem to be pretty much on my own, here.  I use Gentoo on a single
desktop computer at home, mainly for developing free software (Emacs).

I've configured the PC with two HDDs in RAID-1 (mirrored), and I run
logical volume manager.  I keep the box aggresively up to date, synching
portage almost every day.

One of these days, I'll get around to installing Gentoo on a dusty old
laptop I've got.

Putting email on the Atom using IMAP might not be the best option. IMAP can be 
quite heavy on resources on the server-side.

I use a quad-core AMD for my server.

Installed it in a VM now, and followed the wiki ...

I don't even get a console so far, some strange timeouts somewhere.

First steps:

added network.service and sshd.service

following

http://en.gentoo-wiki.com/wiki/Systemd#Services

sshd.service gets started at boot, network.service not ...

I linked multi-user.target to /etc/systemd/system/default.target, didn't
help.

Do I need that link?

Starting network.service with systemctl works, so no typo hidden here,
as it seems.

Solved, but dunno if done correctly.

ln -sf /etc/systemd/system/network.service
/etc/systemd/system/multi-user.target.wants

Re: [gentoo-user] systemd

[Stefan G. Weichinger]

Yes, I know, I should start a new thread.

So far I got the impression that it would take quite some time and work
to get my machines and their services configured correctly.

For now I will keep it inside that ~amd64-VM and continue to test and learn.

Stefan

[gentoo-user] systemd

[Stefan G. Weichinger]

Ok then, separate thread ;-)

I just watched this:

http://www.youtube.com/watch?v=TyMLi8QF6sw

while I continued testing systemd in my VM.

The VM runs ~amd64, so far only a few services started (I still get my
head around how to enable/disable specific services/targets), and it
boots really fast.

I am not the ricer-kind-of-gentoo-users, but it impresses me anyway.

And I clearly see the benefits of socket-based-activation,
cgroup-control and other stuff systemd brings.

AFAI see the wiki mentioned is a starting point only.
It provides the first steps, but not much more, at least to me, right now.

-

There is a layman-overlay "systemd" which brings units (service-files)
to your system. AFAI understand it is still up to the user to
enable/link these files into their runlevel?

If it is that way it feels like a bit of trial-and-error to me to get my
systemd-setup doing the same things my current openrc-system does.

Especially for not-so-trivial stuff like the network settings for KVM
(bridging, TUN/TAP ...)

My approach would be to "rc-config show", take that list and try to
enable the according services within systemd.

Maybe I am completely wrong, maybe not.

I'd be happy to discuss these things with you gentoo-users.

Thanks, greets, Stefan

I use it on my webserver, my Desktop and quite new on the Desktop of my

Now Gentoo does exactly as told and everyone is happy.

Great Video, thanks for the Link.
I wanted to try systemd for quite some time but now I think that I will
install it on my Desktop-PC tomorrow. The summer here this year is very
wet, so leaving the house is not really fun so I have time to kill.

Depends on how you use it. I have an IMAP-Server running on Atom which
holds my email archive. Also depends on the Software you use for the
IMAP-Server.
I can not see why a N270 could not serve a moderate amount of users on IMAP.

Concerning the "Atom not fast enough for compiling"-Problem. I compiled,
run and update a Gentoo System on a AMD Geode LX, which is way less
powerfull and it works just fine.

That's just plain masochism. I have one of those and even installing from
binary packages is painfully slow.

I have three Atom machines here, a small server, a netbook and a nettop
used as a MythTV frontend, and the only compiling any of them do is for
their kernels.

This may help.  I saw one Atom CPU in the list.

It must be pretty slow since it is at about the bottom of the list.  The

I am not sitting in front of it watching stuff scroll by and its
funktion (Wifi-Accesspoint) is not affected by compiling...
Sure it takes a little longer, but why should i care.

And compiling on the Atoms is not worth a mention... my pentium m is
less snappy.

Interesting, thanks! I was interested in a comparison of compile times. I
was originally going to ask how long it takes to compile OO/LibreOffice but
then figured your system most likely didn't have it. haha

And as you said in your other reply, if you rarely have to interact with
this system, and compiling doesn't result in significant lag, why not
compile it? It'd take a century to emerge an entire feature-full
desktop/server build, but as a small embedded system it actually sounds
reasonable.

huh, that's a pretty neat site, thanks. A funny thing about this site is
that the 'slowest' core listed is a P2 which has an estimated compile time
that's twice as fast for gcc as Norman's Geo. His atom is quite snappy
though. :)

Most of the time, there's no need. There are times when a package is
updated and needs a config update immediately after or you could end up
with the new program being called with the old config. Binary installs
mean you have a better idea of when that will need to be done.

It's not a big issue, but I already have the binary build setup so adding
one more host was a simple matter of creating a directory for the chroot
and adding the host name to an existing script.

How long did the initial install take on the Geode? I installed to the
chroot on the build host in the first place then rsynced everything
across.

Yes, and when i return to that shell some time later i scroll through
the package messages and do what needs to be done, followed by a
etc-update, revdep-rebuild, depclean and sometimes lafilefixer.
I am not saying, i update like fire and forget :-).

Everyone should use a setting that one sees fit. That's why we use
Gentoo, right? Because we have that choice.
If you have a well working setup in place, then it is only right to use it.

Can't remember how long it take exactly, but here is the ouput of a
whole system rebuild with a kind of funny estimate :-).
Shows you all the packages, too.
Just wondering myself right now, why there are N and U packages, when
emerge -uDN world shows nothing to do...

emerge -pe system world | genlop -p
These are the pretended packages: (this may take a while; wait...)

I have an Atom 330 machine which is getting significantly worse
build-times than you. What make.conf options are you using? (Or are
you using something else to improve build times?)

     Wed Mar 16 04:49:09 2011 >>> sys-devel/gcc-4.4.5
       merge time: 2 hours, 56 minutes and 20 seconds.

     Thu May  5 22:07:36 2011 >>> sys-devel/gcc-4.3.4

       merge time: 2 hours, 28 minutes and 17 seconds.

Admittedly, my machine runs xbmc, which is a resource hog, and has a
fair bit of disk activity.
My CFLAGS are:
CFLAGS="-O2 -march=core2 -mtune=generic -fomit-frame-pointer -pipe
-mssse3 -mfpmath=sse"
which date to before -march=atom, and having read a performance
article suggesting these. I note that the only practical difference
between the resultant gcc options is that setting -mtune to core2 adds
"#define __tune_core2__ 1". I wonder what the practical difference is.
echo | gcc -dM -E - -O2 -march=core2 -mtune=generic
-fomit-frame-pointer -pipe -mssse3 -mfpmath=sse

I suppose, having looked into it this far, I'll merge gcc-4.5 to see
what effect -mtune=atom has.

(I'm not particularly interested in build times, but whether they're a
sign of poor overall performance ... )

Well i use an Atom D510, the core features seems to be quite similar to
yours, with the only difference, that D510 has a graphics unit added.
Here is my make.conf... how many threads are you using in gcc?

CFLAGS="-O2 -pipe -march=core2 -mssse3 -mfpmath=sse"
CXXFLAGS="${CFLAGS}"
CHOST="x86_64-pc-linux-gnu"
MAKEOPTS="-j5"

USE="-X -gtk -gtk2 -qt3 -qt4 -gnome -kde unicode nls -mysql mmx sse sse2
ssse3 acpi hddtemp threads iproute2"

Yes, those work out to the same set as I posted -- the major
difference is that I have USE="gtk gcj", which along with the
additional load probably accounts for the discrepancy. I also have
-j5.

Continued playing and learning and enabled it on my ~amd64 thinkpad.

Networkmanager and gdm work already, sound as well, it was quite easy.
enabled syslog-ng and sshd.socket

Beauty issues:

I get dozens of
/sys/devices/virtual/tty/tty* services running.
Don't know if that has to be that way.

My encrypted /home is now mounted three times. This might be related to
suspend-to-ram and the fact that I maybe should look deeper into how to
cryptsetup within systemd.

So far it works, but it isn't correct and also seems to trigger problems
with waking up from hibernation (multiple password-requests ...).

I will continue exploring other services soon.
Especially how to set up KVM, vmware, and the needed network-bridging etc.

Re: [gentoo-user] systemd

[Stefan G. Weichinger]

next box tested.
Installed systemd on my main workstation now that I understood how to
easily flip back to booting w/ openrc in case of problems.

I heavily use LVM here and this gives me the following issues:

I use lvm.service from the gentoo-wiki:

http://en.gentoo-wiki.com/wiki/Systemd#LVM

For sure I enabled it ...

When I boot this machine it boots up to starting the LVM-devices and
waits for some time then writes something like:

welcome to emergency mode ...
Start of /dev/VG...something failed (due to some dependencies)

(for all the LVs)

and lets me login or press Ctrl-D to continue.

(I can't remember the exact words, don't know if they are logged somewhere)

When I press Ctrl-D all the LVs are mounted(!) and it boots up fine to
graphical login.

hmm.

It then tells me:

# systemctl status lvm.service
lvm.service - Linux Volume Manager
	  Loaded: loaded (/etc/systemd/system/lvm.service)
	  Active: active (exited) since Mon, 22 Aug 2011 09:55:36 +0200; 22min ago

vg_name --noheadings --nosuffix 2> /dev/null) (code=exited, status=3)
	 Process: 5861 ExecStart=/sbin/vgchange --sysinit -a ly (code=exited,

	 Process: 5654 ExecStart=/sbin/pvscan --ignorelockingfailure
(code=exited, status=0/SUCCESS)
	  CGroup: name=systemd:/system/lvm.service

Why does that ExecStop fail? Why is it called at boot anyway?

I also tried another lvm.service from the russian gentoo-wiki, that
servicefile just pulls in /etc/init.d/lvm, but that didn't help so I
went back to the mentioned file.

What I wonder: what changes between running into that timeout and my
pressing Ctrl-D?

Thanks for helpful comments, Stefan

To me it seems that the underlying RAID-device (which is the PV inside
the LVM-VG) isn't up fast enough.

Trying to figure it out now.

Are they actually started in the right order?
In other words, first RAID, then LVM?

I don't know ;-)

I still try to understand all this.
There is no specific RAID-service-file, so it seems to be done by udev
and the related target/service somehow.


lvm.service says

After=udev-settle.service

so udev should detect all devices first, then lvm.service gets started.

But somehow this doesn't work here, only after hitting that timeout one
time.

That's unfortunate. The stop-service might be started to try to clean up when 
it fails.

What kind of RAID are you using? Does it perhaps rely on a module that is 
loaded in the background?
In which case you could try adding that module as a dependency?

This is plain RAID1 and the kernel has that built in, so no, there is no
module used here for RAID.

There are LVM-options as modules:

crypt target, snapshot target, mirror target ... but that should not
play a role here.

Not really, unless you actually have any of these defined...
I do hope you can figure this one out as I do like the idea of systemd. But I

Got it.

Compared this one:

https://github.com/falconindy/initscripts-systemd/blob/master/lvm.service

w/ the lvm.service in the gentoo wiki.

The line:

Requires=udev-settle.service

missed, I added it and now it boots up straight and fast.

Gotta re-test it right now ;-)

additional thoughts:

preload:

http://packages.gentoo.org/package/sys-apps/preload?arches=all

Maybe, if you want to group stuff you're running yourself into seperate 
groups. The different services are grouped already.

What kind of warnings? Systemd already mounts the filesystem for it and starts 
poulating it. If your script does similar things, they might try to duplicate 
work?

I think it is more useful on desktops and laptops, which get rebooted 
regularly. On a server that tends to run for months without a reboot, a fast 
init-system is important.

And I don't really see the point of D-BUS on a server either. All the services 
that need to talk to each other already have working communication paths.

I do intend to implement it on my desktop and netbook as I'd like to have 
those booting as fast as possible.

I always had the impression that things started faster with preload,
yes. Might be less of an impact with the new SSD I have in my desktop
machine now.

I didn't really miss it when switching to systemd (where I don't have a
service-file for it yet).

The code tries to write to its own dir:

mkdir -p -m 0700 $cdir/user/$$ > /dev/null 2>&1
/bin/echo $$ > $cdir/user/$$/tasks
/bin/echo '1' > $cdir/user/$$/notify_on_release

But somehow the mkdir seems to fail as I get warnings from the two
echo-statements, that their "target-files" do not exist, which lead me
to the fact that $cdir/user/$$ does not exist.

You could try adding ls-statements to see if it can set that op?
Or try to run those commands.

/sys/fs/cgroup which exists.

I removed the "> /dev/null..." part and now I see that I have a
permission problem, my user isn't allowed to mkdir there.

Will solve that ...

otoh it might be overkill to create my own cgroups as systemd does it
anyway, correct?

Rather easy to see:

http://en.gentoo-wiki.com/wiki/Improve_responsiveness_with_cgroups

brings the script /usr/local/sbin/cgroup_start which is started by
openrc, but not by systemd. In there the perms would be set up for my
user ...


So the solution will be to teach systemd to start that script as well.

Reading that blog entry I found discouraging the idea that dbus might be required on my servers in the future, if systemd becomes popular with distros.

I don't see the problem with D-Bus. It's small (the only hard
dependency it has is an XML parser), and it provides the Linux/UNIX
(de facto) standard interprocess communication system.

What's your objection to dbus? It gives you a standard message bus, is 
small, light, consumes minimal resources and provides a nice standard 
way to do IPC. Probably easier than reinventing the wheel with named 
pipes and other bits over and over.

Now if it had similarities to say hal, I would instantly understand. 
But dbus is good and useful in all the ways that hal isn't.

Wasn't. HAL is dead. From http://www.freedesktop.org/wiki/Software/hal

"HAL is in maintenance mode - no new features are added. All future
development focuses on udisks, upower and other parts of the stack.
See Software/DeviceKit for more information."

HAL was an experiment, and it failed. At some point, dbus was an
experiment, and I think it succeeded. Most technologies (KDE, GNOME,
pulseaudio, udev, devfs, ALSA, systemd, upstart) start as experiments.
Some fail, some succeed, and some are replaced by even newer
experiments.

It's the only way new and interesting stuff gets created.

Sadly, HAL is not yet dead. It lives still.

It lives on the production database server I just happen to be 
rebooting as I type this (another story for another time) and will 
continue to live here for a very very long time indeed.

Dale can confirm this. Dale will swear in a court of law with hand on 
bible than hal lives on in zombie form, infesting all the matter of 
his house and computers, infecting them with their undead zombieness.

Ye gods, it's been a long hard day....

I remember getting rid of HAL in one weekend, from all my computers.
It was a long weekend, but it was not as bad as getting rid of Qt from
all the computers in my office some years ago.

WHY is HAL installed on a database server?
I still see desktop systems with HAL, last on an newish kubuntu of a
friend, but on a server? For what is HAL needed there?

Come to my work place, I have the perfect task for you:

to excise perl-5.8.0 from all the many machines it's on, plus the 
atrocious in-house coding using it that no-one left understands, and 
all running on hardware that no-one can replace.

I wish I knew why. The fellow that did the install might know. I'm 
betting it's because he clicked yes, yes, yes, yes, ok on the RHEL 
install CD dialogs.

I can't fix it without running afoul of the Change Management process, 
and today's emergency reboot didn't leave me any time to poke around 
and determine the effect of removing hal.

This is how life in corporate IT works....

	I hate Corp CM and it's one of the reasons I stay in startups. It's job

emergency.

Haven't read the pdf yet, but I just have to share this joke.

Tonight's CM was an unscheduled emergency reboot. This gave me 
opportunity to do something I've been dying to do for ages, enter 
this:

Install plan: reboot server
Test plan:    ping server
Backout plan: unreboot server                 <====== :-)

On the whole our CM process is sane. The manager knows how 
infrastructure works:

If that undersea optical link goes down, I'm fixing it right now and 
to hell with the paperwork and process.

Contrast with my gf's job at the bank. That one truly is a case where 
to change anything, she has to invent imaginary catastrophic 
emergencies. More often than not, she causes them in undetectable ways 
just to get her job done.

That was no big problem ... solved.

Interesting observation right now:

Wanted to extend a LV.

Unmounted it, "lvresize -L+5G ...", then "resize2fs ..."

resize2fs told me that the LV is mounted and that is has to do online
resizing.

whoa. I unmounted it before!

So it seems as if I would have to stop the related mount-service within
systemd first ...

That is an important thing to know IMO.

You can resize a partition without having to umount it first.

That's been possible for a couple of years now. :)

Except for me. dbus-daemon often uses 10-20% of my CPU according to top. And 
this morning, it was using about 750M of memory. Which is less than kwin's 
and Kontact's usage, but still.
But I think the problem is on my side, I run KDE4 with only 8G of memory, no 
wonder I need 1.7G of swap right now.

Mine idles most of the time, no CPU is used. My computer is running for ~6h 
now, dbus-daemon used less than 1.5s CPU time.

Strange. Mine uses only ~20MB.

I have only 4GB of memory, run kde4, swap is not used at all most of the time. 
There are still ~512MB free with ~1,3GB cached currently.
I do have programs running :) firefox with some tabs, kdevelop with a project 
(~100.000 LOC), kmail, LibreOffice and 3 konsoles, each with some tabs open.
I know, I am of no help at all, but I really wonder, why your numbers differ so

Kinda similar here: GNOME 3.0, Emacs with several LaTeX articles,
Evince, Evolution, Rhythmbox, Chromium with like 20 tabs (my 4 zombie
processes are Chromium tabs), and the heaviest of all, Inkscape with 6
different SVG pictures.

There is something really wrong with Alex D-Bus; but I don't think
it's the bus. Probably some program is spamming the bus, making it use
that much memory, but I don't know for sure.

After a relogin, this is also true here at this moment, dbus-daemon uses 
about 4% of one of my two cores. After 26 days of uptime, its total CPU time 
is 1380 minutes, Followed by udisks-daemon with 990 minutes, and then mysqld 
with 25 minutes.

Right now I have three dbus-daemon processes (one owned by messagebus, two 
owned by my user), with a total of 4.5M only. The excessive usage of 750M (I 
noticed this for the first time) probably was a memory leak. Like with KWin, 
where it always happens after some days of being logged in.

I run some more applications. 9 Konsole tabs, two Dolphins, a Konqueror as 
file manager, Amarok, TV-Browser, Kontact, Chromium with 15 tabs, KMyMoney. 
That's what comes up after login, after a while of being logged in more 
stuff is running. Yesterday I had a Windows running in vmplayer, that may 
use 512M.
Right now, 4.7G of memory is needed (free -m, -/+ buffers/cache entry).

[Later]

Whoops, forgot to actually send this mail. Ten hours later I have another 
dbus-daemon process, owned by root, but memory their usage is the same. 
5250M of RAM are needed now altogether.

Very, very weird. You all seem to have some weird issues with
dbus-daemon that I don't have.

(times retrieved with ps axS, memory consumption retrieved with htop)

On my 77-day uptime server runing Debian 5, dbus's total time is 0:00.
(That's with ps axS) virtual memory of 21M, resident of 900K.

On my gentoo desktop, 8 days' uptime, I show two dbus-daemon
processes, both with 0:00. Both with virtual of 19M. One with resident
of 984K, one with resident of 808K.

On my router, Debian 6, with 4 days' uptime, ps axS shows 0:00 for
consumed time. 23M virtual, 968K resident.

He probably has the same problem as I - something badly wrong in the
roll-your-own config.

I had a 4G Dell laptop where KDE would start and instantly consume at
least 1.5G just for it's various bits. Akonadi, Nepomuk, Virtuoso were
the usual culprits. Oddly, dbus would often rise to 700M (!). And
forget about actually emerging something - the first sniff that gcc was
running and the machine would thrash like mad and 4G swap would fill up
in no time at all. Less sweap wasn't an option - the battery is dud so
I needed hibernate.

Sadly (or not, depending on your viewpoint), that machine died on
Monday morning - suspect graphics card. I can't complain - it ran flat
out 24/7/365 and I treated it like one of the servers that I could
carry around. So I can't even troubleshoot what I configured how to
make performance behave like it did.

Happily, there was a nice pretty lady from Samsung in the office 3
months ago wanting to sell the 900X Macbook Air knock-off into the
company. The IT manager didn't know what to do with the demo she left
behind so I knicked it for myself (sans paperwork of course. Makes it
easier to prolong how long it takes to test properly) and it's running
Ubuntu. Memory issues are a thing of the past and everything behaves
just like it should. Even <gasp> flash.

That saddens me a little. Of all the friends and coworkers I have, I'm
the only one left using Gentoo. All of them switched to Fedora, or
Ubuntu, or OpenSuSE.

My three years old laptop runs up-to-date Gentoo with systemd, plus
the GNOME overlay so I can use GNOME 3. Absolutely everything works
with the laptop: the Wi-Fi with NetworkManager, the sound with
PulseAudio, suspend/resume, all the Fn keys, wathever. Even the
ridiculous touchstrip fingerprint sensor, though I don't really use
it.

Even more: every damn GUI program does what it should, so even though
I'm able to configure and use everything with the command line, I
don't have to, because I can use the pretty graphic programs... if at
all, 'cause nowadays everything usually "just works". And the same
it's true for all my other machines.

But I'm also aware that all of this is possible because I have the
knowledge (and the patience) to detect and fix any problem that I may
encounter when updating my machine. I don't need a robust QA from my
distribution, but I'm the exception. And this is the kind of QA
problems that make people to replace Gentoo for Ubuntu, or Fedora, or
whatever.

I whish I knew how to solve this so everybody could use Gentoo, but I
don't. I don't think I will ever use any other distro (although I've
toyed with the idea of trying exherbo), but I cannot in good
conscience recommend it to "normal" users, unless I'm willing to be
their tech support forever.

I love Gentoo, been using it since 2004, but I'm the first one to
admit it's not for everyone.

And that saddens me a little.

I completely understand how you feel. But, I'm enjoying this break from
Gentoo. Note I said "break", not "leave behind".

It will take 3 to 6 weeks for me to make up my mind what monster Dell I
want next, assault Purchasing to make them approve it then have it
built in Ireland and shipped to ZA.

That's about enough time I think to run into the Ubuntu "you will do it
our way with the deps we want you to have" philosophy enough times to
drive me back to gentoo. But the next machine will not have KDE on it -
all this RAM nonsense started by trying to get Akonadi to work, for very
loose definitions of "work", such as "show me my mail sometime today"

e17 beckons.

I must have words with Dell!!!

Mine was built in China and shipped from China ... twice, because the 
horrendous courier they use did not deliver it.

I have a laptop which is only used occasionally and (K)Ubuntu is a good use 
case for it.  Keeping it up to date does not take long with more or less 
vanilla Kubuntu settings and because the user needs are not particularly 
demanding Ubuntu has filled the OS role admirably.  Doing this with Gentoo 
would require much more attention and time from me.  However, I would not use 
Ubuntu for my needs.  Very much like Alan says, there is an annoying 
underlying feeling of "all your OS belongs to us".

Let us know which mail client you end up with.  Although I now use e17 and 
before that I used a rather edited Fluxbox (I avoid bloatware DEs if I can 
help it) I am still using kmail because attempts to adopt other mail clients 
ended up in disappointment.

At the moment I'm using claws and it seems quite fine. It has it's
funnies (mostly just different behaviour from kmail actually) so I need
to rewire my brain a bit.

It wants to wait for me to manually expunge folders, and I haven't quite
figured out how to always get it to use the correct .sig (a few times
my work .sig got used on mailing lists where I always use gmail), but
claws has these two amazing features that make it a killer app for me:

- it will not ever compose html mail but does a decent job of display it
when received
- it actually sends, receives and stores mail (akonadi users will
  appreciate how a mailer can get to make that insanely more complex
  than it needs to be)

I *really* like Claws Mail, I never liked KMail. In fact, removing KDEPIM
is the best way to improve KDE.

Set up a different (SMTP-only if necessary) account for each address and
specify the sig. You can set the default account to use for a folder,
which means you always use the correct address on a mailing list. If no
default account is set, Claws will default to using the account that the

I'm so glad I ditched KMail before akonadi and friends came along.

Interesting!  With me it has been the opposite.  I didn't make a list of the 
things that really bothered me with Claws, but after a dozen use cases of me 
saying "why can't Claws behave like Kmail?" I gave up and went back to Kmail

Akonadi and all the bloatware that came with KDE4 has been a major 
disappointment and cause of annoyance for me.  Thankfully, after some initial 
teething problems with sqlite (I don't use mysql on my laptop) akonadi has not 
given me any trouble - but I am worried about what is coming when reading 
Alan's experience!

Have I understood this correctly that Kmail2 will no longer store messages in 
conventional maildir files and it will all be stored in database tables?

Well, if you want a program that behaves just like KMail, KMail is
probably the best choice...

I like to use local IMAP folder and route all mail into those,
organized by work and other. I found that I can set prefs for a top
folders and all children folders which handled this one nicely.

"The mythical man-month" by Brooks perfectly describes akonadi, they
went right ahead and made every mistake in the book, especially all the
ones solved in the 70s already,...

To be fair my problems started after migrating a setup that had come
along since early-KDE3 days and went through many pre-release versions
of akonadi. Almost everyone I found with major problems was in the same
boat while people who did fresh installs on SuSE and Fedora were fine.
Observe that clkean new install is not a valid use-case for a gentoo
user

No, akonadi functions as a giant cache. The backing store for mail is
still mbox, MailDir, IMAP or whatever and used as normal. Akonadi
stores meta data about the mail (maildir index files are not in files
for example, they are in Akonadi). Contacts and calendars are still on
disk with a cached copy in Akonadi. 

Full text searches of mail bodies is stored in Nepomuk.

So do I. In Claws, folders and accounts are entirely separate - you can
have mail from various accounts in the same IMAP folder tree.

It might be old but every word in it is still just as true as the day
it was written. Nothing else has come close to doing it like Brooks.

I found my copy in a tiny out of the way junk shop in a place called
Memel (at the arse end of the world), priced at about a cup of coffee.
A treasured find indeed :-)

You've got me intrigued now. I haven't used Claws since an early, unstable 
version, but it looks as though it might suit me now.

First, though, does it have an easy bulk import mechanism from KMail format? 
I have over 10,000 mails here in about 50 folders, and I really wouldn't 
want to go through that lot one by one.

It doesn't support KMail folders directly (Claws doesn't do traditional
MailDir, it's native format is MH) but you can find import scripts here:

http://www.claws-mail.org/tools.php?section=downloads

There are kmail-specific scripts listed

Except that, when I ran the converter script and restarted Claws, the folder 
structure had been duplicated but they were all empty. I have another head-
scratching opportunity...

Re: [gentoo-user] systemd

[Stefan G. Weichinger]

Didn't do much research around this lately.

Today I revived my SSD (we'll see) and therefore fell over systemd when
I edited grub.conf

Where would/should I put stuff from /etc/local.d/ with systemd?

I have some commands there setting parameters for ssd-usage and those
would be skipped (not executed) with systemd.

Pls don't misunderstand, this is not gentoo ricer stuff, I am quite
happy w/ openrc, especially w/ the ssd.

Those command are on a script, right? Lets say the script is called
ssd-thingies; you put this on
/etc/systemd/system/ssd-thingies.service:

----------------------------------------------
[Unit]
Description=SSD thingies
After=basic.target

[Service]
Type=oneshot
ExecStart=/my/path/to/ssd-thingies

[Install]
WantedBy=multi-user.target
-----------------------------------------------

Then you run:

systemctl daemon-reload
systemctl enable ssd-thingies.service

Next time you reboot, the service will be called after the
basic.target has been completed. You can look at the status of the
script afterwards with

systemctl status ssd-thingies.service

If everything went OK, it should have a line like this:

Process: 1234 ExecStart=/my/path/to/ssd-thingies (code=exited, status=0/SUCCESS)

Thanks for the explanation!

I tried it right now, unfortunately I get:

# systemctl status ssd-thingies.service
ssd-thingies.service - SSD thingies
	  Loaded: loaded (/etc/systemd/system/ssd-thingies.service)
	  Active: failed since Tue, 11 Oct 2011 23:28:05 +0200; 21s ago
	 Process: 6696 ExecStart=/etc/local.d/stefan.start (code=exited,
status=203/EXEC)
	  CGroup: name=systemd:/system/ssd-thingies.service

Is it a permission-issue? AFAIK systemd runs w/ root?


# cat /etc/systemd/system/ssd-thingies.service

[Unit]
Description=SSD thingies
After=basic.target

[Service]
Type=oneshot
ExecStart=/etc/local.d/stefan.start

It runs as root, but it's already telling you the problem:

> Process: 6696 ExecStart=/etc/local.d/stefan.start (code=exited, status=203/EXEC)

Your script (I believe) does not have execution perms. All the
commands for ExecStart (and ExecStop) need to be executable, so do a

chmod +x /etc/local.d/stefan.start

Also, if your scripts does not return 0 (or the last command it
executes does not return 0), it will tell you with the status= flag.

I showed you before:

Sorry, didn't see it. Can you execute it calling it directly? Maybe
it's missing the proper shebang.

I really think is that systemd cannot execute it, but check that also.

The shebang did the trick!

Hello, 

I have a short question to systemd. I would like to ask your experience

Change or reinstall? What mean the profis here?

Thank you for help and have nice weekend.

It's pretty straightforward, just follow the wiki. The profile takes care of setting the appropriate USE flags. One thing to watch out for is that systemd will not pick up your openrc startup services so save the output from rc-update - s then enable the services after changeover .
