   5 <p>A few days ago, parallel booting was enabled in Debian/testing.
   6 The feature seem to hold up pretty well, but three fairly serious
   7 issues are known and should be solved:
   8
   9 <p><ul>
  10
  11 <li>The wicd package seen to
  12 <a href="http://bugs.debian.org/508289">break NFS mounting</a> and
  13 <a href="http://bugs.debian.org/581586">network setup</a> when
  14 parallel booting is enabled.  No idea why, but the wicd maintainer
  15 seem to be on the case.</li>
  16
  17 <li>The nvidia X driver seem to
  18 <a href="http://bugs.debian.org/583312">have a race condition</a>
  19 triggered more easily when parallel booting is in effect.  The
  20 maintainer is on the case.</li>
  21
  22 <li>The sysv-rc package fail to properly enable dependency based boot
  23 sequencing (the shutdown is broken) when old file-rc users
  24 <a href="http://bugs.debian.org/575080">try to switch back</a> to
  25 sysv-rc.  One way to solve it would be for file-rc to create
  26 /etc/init.d/.legacy-bootordering, and another is to try to make
  27 sysv-rc more robust.  Will investigate some more and probably upload a
  28 workaround in sysv-rc to help those trying to move from file-rc to
  29 sysv-rc get a working shutdown.</li>
  30
  31 </ul></p>
  32
  33 <p>All in all not many surprising issues, and all of them seem
  34 solvable before Squeeze is released.  In addition to these there are
  35 some packages with bugs in their dependencies and run level settings,
  36 which I expect will be fixed in a reasonable time span.</p>
  37
  38 <p>If you report any problems with dependencies in init.d scripts to
  39 the BTS, please usertag the report to get it to show up at
  40 <a href="http://bugs.debian.org/cgi-bin/pkgreport.cgi?users=initscripts-ng-devel@lists.alioth.debian.org">the
  41 list of usertagged bugs related to this</a>.</p>
  42
  43 <p>Update: Correct bug number to file-rc issue.</p>
