It was originally UFS. I'd noticed the corruption, and when it proved
too severe for fsck to fix, I wiped the filesystem and started again
from scratch. Reinstalled Oracle, and everything seemed OK, only for
it to then corrupt again almost immeditately. No, I wasn't impressed
when I finally worked out the cause...

Speaking of union mount type things, I've been hearing rumours about
them for Linux for years, but haven't seen any concrete evidence. ISTR
Al Viro muttering something about how to get equivalent functionality
on Linux ages ago. Has anyone played around with it yet? If so, is it
any good?

The other thing I'm looking for is "home directory" mounts. Can't
remember if that's the correct term, but I remember reading about
them. Basically a system to let you have a filesystem mounted in
multiple users' home directories. The original idea behind it
was for mail. You could have $HOME/mail as normal, but behind the
scenes, each user's $HOME/mail was mounted on a shared central
filesystem.

Anyone know of such a thing (ideally for Linux, but just a pointer
to a paper or something would be nice)?
