I can't really imagine how that would happen aside from file system
corruption. You can't usually create hard links to directories, though I
believe some UNIX systems *might* allow root to do such a thing. Have you
run an fsck on the file system in question? Can you actually find other
directory entries pointing to the same inode ('ls -li fobsolete' and 'find
-inum ...')?

I have no idea how that would happen, but *as root* you can remove them with
'chattr -i ' (or even 'chattr -R -i trash'). Since the attribute
can only be set or cleared as root, it seems unlikely that BackupPC set it.
Maybe file system corruption? I'd run an fsck just in case. Did this happen
only once or are you constantly getting more and more immutable directories?
Talking about fsck, does anyone know if fsck has problems with BackupPC-pool-
type file systems (large link counts, links spread across many directories)?

Someone with a better understanding of hardlinks and BackupPC can probably expand on this, but it is my guess that something happened out of order or was interrupted preventing the correct unlinking of the directories. You might take a look at what is in the trash directory to see if you have a similar situation. I haven't figured out how to remedy this yet.
