Did you try running insserv by hand to restore the links?  Did
the maintainer scripts restore any of the links for you?

If you're referring to the commit above, it's because we've fully
transitioned to dependency-based boot for wheezy, so the hardcoded
runlevel ordering isn't used any more (at all), even for file-rc.
Note that file-rc was also updated to use insserv, so it too was
also using dynamic ordering.  So the above removal should have had
zero effect upon use of either system--both systems were already
using the "defaults" option implicitly.

The real problem here is probably that the maintainer scripts for
handling the transition between the file-rc and sysv-rc systems
may not be doing their job robustly.  It should be possible for
it to transition seamlessly between the two since they are just
describing the same stuff in a different way.  This is probably
a bug in the file-rc prerm/postrm and/or the sysv-rc
preinst/postinst.  IIRC file-rc should restore the sysv-rc links
and sysv-rc should make sure insserv is run again.  If any
file-rc users could investigate this in more detail, that would
be much appreciated.  I thought this was all working for wheezy
from my own testing of it in VMs, but I'm not a file-rc user,
and there may be cases where the configuration isn't being
