[lug] cruft from an fsck'ed partition

[Hugh Brown]

Let me add more detail.  On fileserver I have a partition that is mounted
on /home it has an appropriate lost+found directory.  Once a week, I do a
backup of fileserver:/home to backupserver:/backups/fileserver/home

On backupserver I have a large partition that is mounted at /backups

I do the backup by doing a tar cf - /home  | (cd /backups/fileserver; tar
xf -)   all over an ssh session.  

I was looking at the backup (a user typed rm * in her home directory, oops)
and noticed  the block file where a directory should have been.

I tried to delete it and got all of what I noted below.

I think it ended up that way as a result of fsck trying to fix things after
a system crash.

How can I remove the block special file?
