I'm not really sure about this.  AFAIK, upstart is ubuntu invention.
I believe (but I must admit that I am not really sure) that I've seen
the same problem with debian.  AFAIK, debian don't use upstart (yet).

One more point: I remember long ago (debian 1.x or something), I was
never sure what to do when fsck failed on startup.  That was because
whatever I did, the result was never what I expected.  At those times
I thought it was me (as a newbie) who did something wrong.  But now
I am pretty sure I have tried every reasonable command, and IMHO _every_
of the tried command _should_ have rebooted the system.  But _none_ of
them really did the trick.  So I strongly believe that there's something
