that's a system configuration error.

what happens on unix when you ave a file owned by a uid or a gid that
isn't in /etc/passwd or /etc/group?

1) ls -al shows numbers not names

2) only root can change ownership of the file.

well, we can't do an equivalent to 1) in the "unknown" circumstances, with
SURS.  so throw an error: let the app deal with it [access denied].
