It won't; unlink() removes files, rmdir() removes (empty) directories,
remove() removes either. There is no system call or library function
to delete a directory tree.

That's a useful point; "mv" and rename() will rename an entire
directory tree with no complaints.

The only "rm -rf" commands in etc/Init.sh shouldn't be able to remove
the wrong directory even if $tmp is unset or there were problems in
constructing its value.

The current clean_temp program only deletes files, not directories
(not even empty ones).
