In grml64 daily sid builds starting with at least May 19 (not sure about before
that), the bootup process runs pretty much every init script that grml comes
with.  It never gets to finish it (at least in my testing), because after a few
minutes of booting up, some script goes into a restarting loop and init decides
to wait 5 minutes before attempting to start it again.  I can systematically
reproduce it on different systems, regardless of boot media.
