Normally, it doesn't have to drop to a shell. As you know, if you sync
your drives and shutdown cleanly, all the data that's pending will be
written to disk and the boot will be clean.
Did the other filesystems require fixing at all?
I"ve only had fsck drop to a shell a couple of times, so it's pretty
rare, and you have to be working the disk really hard when the
thing reboots. One time it happened to me was when the power went out
during a Cnews expire.

Ones that require fsck to drop to a shell -- I'd say no.

Quite possibly. ext2 is very robust. In the example power failure I
cited, it dropped me to a shell and worked the disk for what seemed like
ages before it finished.
When I got back control of the machine (some 30 minutes later .. but
this was on a slower system) I had two files in lost+found, and those
were articles that were scheduled for deletion anyway, so I deleted them. :)
Considering that files in lost+found are roughly the equivalent of DOS's
FILE0000.CHK or FILE0000._DD (the latter if you use Norton Disk Doctor),
I'd say ext2 is _really_ robust. One can get those DOS files several
times a day. :(
