+Title: Debian boots quicker and quicker
+Tags: english, debian
+Date: 2009-06-17 14:20
+
+<p>Monday and tuesday I spent in London with a lot of the people
+involved in the boot system on Debian and Ubuntu, to see if we could
+find more ways to speed up the boot system.  This was an Ubuntu funded
+developer gathering. It was quite productive.  We also discussed the
+future of boot systems, and ways to handle the increasing number of
+boot issues introduced by the Linux kernel becoming more and more
+asynchronous and event base.  The Ubuntu approach using udev and
+upstart might be a good way forward.  Time will show.</p>
+
+<p>Anyway, there are a few ways at the moment to speed up the boot
+process in Debian.  All of these should be applied to get a quick
+boot:</p>
+
+<ul>
+
+<li>Use dash as /bin/sh.</li>
+
+<li>Disable the init.d/hwclock*.sh scripts and make sure the hardware
+   clock is in UTC.</li>
+
+<li>Install and activate the insserv package to enable dependency
+   based boot sequencing, and enable concurrent booting.</li>
+
+</ul>
+
+<p>On our IRC channel for this effort, #pkg-sysvinit, a new idea was
+introduced by Raphael Geissert today, one that could affect the
+startup speed as well.  Instead of starting some scripts concurrently
+from rcS.d/ and another set of scripts from rc2.d/, it would be
+possible to run a of them in the same process.  A quick way to test
+this would be to enable insserv and run 'mv /etc/rc2.d/S* /etc/rcS.d/;
+insserv'.  Will need to test if that work. :)</p>
+
+<p>Support for makefile-style concurrency during boot was uploaded to
+unstable yesterday.  When we tested it, we were able to cut 6 seconds
+from the boot sequence.  It depend on very correct dependency
+declaration in all init.d scripts, so I expect us to find edge cases
+where the dependences in some scripts are slightly wrong when we start
+using this.</p>
