Hello,
I surely missed something, but I have no clue why.

I had to switch off (in a quite unexpected and rude way) my laptop (i386 
- 3.99.8). When I switched it on again, the automatic fsck checks failed.

fsck -p fails because it complains about no lost+found directory, and 
fsck_ffs reports an inode out of range and quits at pass2 (checking 
pathnames). When I did a fsck on the other partitions, it seemed that 
every directory had to be reconnected.

Anyhow, I couldn't get any clean file system and I had to mount them 
stale, which is how I send this mail. The system does not seem to run 
into inconsistencies, I can execute X and Mozilla, but it is quite 
unsettling to know that fsck does not work. I suspect I missed something 
like a file system update, but when or where?

Thanks for any help.
Vincent
