SubjectProblems umounting root fs
Whenever I do a proper shutdown on my system (using the attached
rc.0/rc.6 script) there is always one inode that ends up with zero
dtime. I know this since (now that I have discovered the problem) I
have set up my rc.S to force an fsck on the fs every reboot. I am
posting this problem here since the script properly syncs and umounts
the fs, and thus I suspect that this is a kernel-level problem. Has
anyone else seen this problem? Am I just doing something uninformed (as
opposed to stupid :) )?
