  24       <div class="date">24th June 2009</div>
  25       <div class="body"><p>I spent Monday and tuesday this week in London with a lot of the
  26 people involved in the boot system on Debian and Ubuntu, to see if we
  27 could find more ways to speed up the boot system.  This was an Ubuntu
  28 funded
  29 <a href="https://wiki.ubuntu.com/FoundationsTeam/BootPerformance/DebianUbuntuSprint">developer
  30 gathering</a>. It was quite productive.  We also discussed the future
  31 of boot systems, and ways to handle the increasing number of boot
  32 issues introduced by the Linux kernel becoming more and more
  33 asynchronous and event base.  The Ubuntu approach using udev and
  34 upstart might be a good way forward.  Time will show.</p>
  35
  36 <p>Anyway, there are a few ways at the moment to speed up the boot
  37 process in Debian.  All of these should be applied to get a quick
  38 boot:</p>
  39
  40 <ul>
  41
  42 <li>Use dash as /bin/sh.</li>
  43
  44 <li>Disable the init.d/hwclock*.sh scripts and make sure the hardware
  45    clock is in UTC.</li>
  46
  47 <li>Install and activate the insserv package to enable
  48    <a href="http://wiki.debian.org/LSBInitScripts/DependencyBasedBoot">dependency
  49    based boot sequencing</a>, and enable concurrent booting.</li>
  50
  51 </ul>
  52
  53 These points are based on the Google summer of code work done by
  54 <a href="http://initscripts-ng.alioth.debian.org/soc2006-bootsystem/">Carlos
  55 Villegas</a>.
  56
  57 <p>Support for makefile-style concurrency during boot was uploaded to
  58 unstable yesterday.  When we tested it, we were able to cut 6 seconds
  59 from the boot sequence.  It depend on very correct dependency
  60 declaration in all init.d scripts, so I expect us to find edge cases
  61 where the dependences in some scripts are slightly wrong when we start
  62 using this.</p>
  63
  64 <p>On our IRC channel for this effort, #pkg-sysvinit, a new idea was
  65 introduced by Raphael Geissert today, one that could affect the
  66 startup speed as well.  Instead of starting some scripts concurrently
  67 from rcS.d/ and another set of scripts from rc2.d/, it would be
  68 possible to run a of them in the same process.  A quick way to test
  69 this would be to enable insserv and run 'mv /etc/rc2.d/S* /etc/rcS.d/;
  70 insserv'.  Will need to test if that work. :)</p>
