  24       <div class="date">13th May 2010</div>
  25       <div class="body"><p>The last few days a new boot system called
  26 <a href="http://www.freedesktop.org/wiki/Software/systemd">systemd</a>
  27 has been
  28 <a href="http://0pointer.de/blog/projects/systemd.html">introduced</a>
  29
  30 to the free software world.  I have not yet had time to play around
  31 with it, but it seem to be a very interesting alternative to
  32 <a href="http://upstart.ubuntu.com/">upstart</a>, and might prove to be
  33 a good alternative for Debian when we are able to switch to an event
  34 based boot system.  Tollef is
  35 <a href="http://bugs.debian.org/580814">in the process</a> of getting
  36 systemd into Debian, and I look forward to seeing how well it work.  I
  37 like the fact that systemd handles init.d scripts with dependency
  38 information natively, allowing them to run in parallel where upstart
  39 at the moment do not.</p>
  40
  41 <p>Unfortunately do systemd have the same problem as upstart regarding
  42 platform support.  It only work on recent Linux kernels, and also need
  43 some new kernel features enabled to function properly.  This means
  44 kFreeBSD and Hurd ports of Debian will need a port or a different boot
  45 system.  Not sure how that will be handled if systemd proves to be the
  46 way forward.</p>
  47
  48 <p>In the mean time, based on the
  49 <a href="http://lists.debian.org/debian-devel/2010/05/msg00122.html">input
  50 on debian-devel@</a> regarding parallel booting in Debian, I have
  51 decided to enable full parallel booting as the default in Debian as
  52 soon as possible (probably this weekend or early next week), to see if
  53 there are any remaining serious bugs in the init.d dependencies.  A
  54 new version of the sysvinit package implementing this change is
  55 already in experimental.  If all go well, Squeeze will be released
  56 with parallel booting enabled by default.</p>
