yeah, I found that out on the KnoppMyth live CD I was using. fsck
from that was segfaulting so I followed another suggestion and
downloaded and ran "Recovery Is Possible" and managed to get fsck to
run with that to completion. It must have been a high level inode
that got roached as most of the filesystem got remapped to
lost+found. /var isn't even a directory 8^( It's there but an actual
file rather than a directory. I've been using grep and find but I'm
not having a lot of luck.
