"Linux also offered financial firms the ability to modify the source
code to further speed performance, Lameter said. "It depends on how
daring the exchange is," Lameter said, noting that NASDAQ uses a
modified version of the Gentoo Linux distribution. "

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.

[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.)

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

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

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 own similar combination (the server is actually head/mouseless desktop powered
by core i7 and equipped with 24gb of ram allowing to concurrently run number of
gentoo and freebsd pv-machines); also renting a small gentoo powered vps running
as mail/list/file server for personal use

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 :-)

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?

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.

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

Which howto did you follow, what do you recommend me to read to start
using it (with gentoo, sure) ?

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

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 ;-)

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.

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.

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

I don't even get a console so far, some strange timeouts somewhere.
getty@tty1.service depends on something I can't see (no way to scroll
up) ... still some fiddling needed here.

In rescue mode I read something about /etc/mtab, google says "ignore that".

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

ln -sf /lib/systemd/system/multi-user.target

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.

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.

- 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.

My usecases for Gentoo are desktop / laptop, fileserver, router, a kvm
guest on my rootserver and an AMD Geode based WLAN-Accesspoint.
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.

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.

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.

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

http://gentoo.linuxhowtos.org/compiletimeestimator/

It must be pretty slow since it is at about the bottom of the list.  The 
list goes from fastest to slowest.

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. :)

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.

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.

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"

LINGUAS="de"
AUTOCLEAN="yes"
FEATURES="parallel-fetch"

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.

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.

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.

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...)

Why not? I've been trying many distributions in the hope of finding one that 
suits me; this is just the latest in the search. It won't last.

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.

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 :)

We should mention this somewhere on the Gentoo page on wikipedia.

I use it on my webserver, my Desktop and quite new on the Desktop of my
mother. I had there Xubuntu before but that was a pain in the rear-end
to administrate with all that fiddly automatisms.
Now Gentoo does exactly as told and everyone is happy.

The next goal is to convert the laptop of my Girlfriend, it runs Windows
7 for now.

Survey answer

Desktop and laptop gentoo. Both for personal use. Desktop hosts webserver for pictures and stuff (keeps the mrs happy) inc samba, kvm,  etc

Been using for 4 years and still haven't got a clue but mailing list has been great for tips and advice and sanity.

Dual boot with windows 7 but only for games. How sad

That's interesting. I run a SheevaPlug with Gentoo onboard. It runs at
1.2G and has half a G of memory. I have no trouble compiling gentoo on
this little server. It works as a file server, backup server, web
server and portage server (distfiles and portage sync for the gentoos on
my network).

Is ARM more efficient than the intel atom?
