I find the fscking on boot rather annoying too, but I think your problem
is either that you aren't waiting for the sync before resetting or you
are having a cache consistancy problem.
To fix the fsck-on-every-reboot problem:
1) Modify the volume header to include a bit defined as the "clean"
bit.
2) Modify "newfs" to set this bit on newly created file systems
just before device close.
3) Modify fsck to check for this bit:
a) If set, perform abbreviated fsck, something like
printing the message "File system clean; skipping
check".
b) If the bit is not set, do the fsck and set the bit
before device close.
4) A successful "mount" unsets the bit.
5) A successful "umount" sets the bit.
No more nasty fsck's!
I will post my patches when I get around to them, but I'm awfully busy
just this instant, and probably will continue to be too busy for the next
several weeks if not an entire month.
