Gentoo's init system already specifies dependencies for services doesn't
it?  Sounds like the biggest hurdle the article's author had to overcome
was the dependencies.

Maybe it wouldn't be a big stretch for Gentoo to start its services in
parallel.

[gentoo-dev] Booting in half the time?

Howdy.

Saw this linked to off of NewsForge today, and thought it'd be great if
  the gentoo boot process made use of the idea.  Essentially, it seems to
  be saying "start services in parallel".

Interesting:

As per <http://bugs.gentoo.org/show_bug.cgi?id=20862> you do:

echo 'RC_PARALLEL_STARTUP="yes"' >> /etc/conf.d/rc

and then restart your system.

Most nifty.  How stable is this?  Is this something that can be safely
used, or is it still experimental? :)

Well, I took the time to restart. It *seems* a bit faster, but that 
doesn't mean anything. It could easily be wishful thinking. Does anyone 
know how to tell if its working, besides comparing the order things 
start with and without that set? Is this even in the most recent ~x86 
baselayout?

It worked well for me - there was a decrease in boot time.. I could not tell 
you by how much, but it seemed to be about 25% quicker. Of course, that could 
just be my expectation of it working and my mind playing tricks.. :-)

I don't have a lot of extras load on startup - I start apache and sql and 
other hogs when I need to do dev work, so it will probably be those people 
with the most items set to load on startup will see the greatest benefit of 
this. Plus, my system is shiny and new so perhaps older systems will also get 
greater benefit of this.

(No problems or issues, for me, either!)

I tried it on my laptop, and it gave me some error messages about scripts
including /etc/init.d/clock, though after boot everything seemed to have
started anyway.

In any case, it didn't seem to speed up boot significantly.  I suppose if
you had dhcp requests going during boot and you weren't on a network, this
might allow other things to boot in the meantime, but I have most
non-essential, time-consuming bootscripts disabled by default.

I updated the config on my laptop and rebooted and it seems to have 
worked. A few glitches came through, for example I saw a message stating 
that "net.eth0 had already been run" while net.eth0 was starting up, so 
I'm guessing the (circular) dependancy checking aspect isn't 100%, but I 
was able to log in.

I'll update my main development machine in the morning (when I'm awake. 
:> ) and see how it goes.

My servers, however, will have to wait a smidge until this is tested a 
lot more thoroughly.

Re: [gentoo-dev] Booting in half the time?

[Josep Sanjuas]

Hallo,

Another idea: we could mark the service xdm (and maybe other services too) as a 'high priority' service, that is to be started as soon as possible. I have no need of sshd and sendmail being run before I can start an X session. Is that feasible? That might save some people a few more seconds.

  Tried it yesterday on my laptop.

  I noticed no change in bootup time but got a couple of warnings about
  services that were already started.

We have this:

# grep -4 RC_PARAL /etc/conf.d/rc
 
# Set to "yes" if you want the rc system to try and start services
# in parallel for slight speed improvement.
 
RC_PARALLEL_STARTUP="yes"

Have some issues:

1) Do not print synced.

2) Sometimes have errors on starting stuff, but they was actually
already started ...

But it *does* start all services, no matter the error now and again.

Not sure - please do:

 # RC_DEBUG=yes depscan.sh

and post your /var/lib/init.d/depcache and /var/lib/init.d/deptree.

Re: [gentoo-dev] Booting in half the time?

[William Kenworthy]

This is one of the downsides of a distributed configuration system -
items exist for a long time before anyone stumbles over them.

Is there a consolidated list of every item one can configure on a gentoo
system and a short description that includes what file they hide in?  I
am thinking of something like a consolidated
conf.d/*;rc.conf;make.conf;make.profile;... with a short description of
each item.

I guess I could do this locally by just cat'ting the files together and
regularyly diff'ing against this to see whats changed.

Well, in theory this is one of the things that CONFIG_PROTECT should
be of some help - you should see if new conf items is added ...
