Just wondering: couldn't it try to umount the filesystem if it's not root ? It would not mount it again without running fsck, it's not clean. Possible problems: Buffer management and file syncing should be flushed in this case, and completely ignore what's in core memory. Jonny -- Joao Carlos Mendes Luis M.Sc.
