Null in directory name

[News Administrator]

My IBM PC/AT Xenix (System III) system went wierd last nite, resulting
in the /usr/bin directory being transmuted into an unreachable directory.
What happened was that the `i' in `bin' was turned into a null, and no
matter what I tried to do, the system kept complaining that 'b' was
non-existant. I ended up remaking the filesystem from a backup.

Was that the only solution, or does someone else have a better way?
