hi peter. i may be misunderstanding the givens, but this does not
sound like a situation that can be fixed within rdiff-backup. if you
are running as a non-root user who does not own the file, you will not
have permission to chmod it in order to read it.
you should be able to verify this on the command line. rdiff-backup is
a filesystem-based backup utility, like tar, and is subject to the
same constraints as the command line (constrast to 'dump' or 'dd' that
bypass the filesystem and only need read permission on the raw
$ cat /usr/local/bin/sudoedit
cat: /usr/local/bin/sudoedit: Permission denied
$ chmod 4115 /usr/local/bin/sudoedit
chmod: /usr/local/bin/sudoedit: Operation not permitted
if i am missing something let me know!
