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