No, I'm not confusing it, and no, the ownership isn't numeric. At least,
in my experience. I've created backups of redhat and fedora installs, in
single user mode, and restore them under live cds (knoppix or self-made).
If I didn't use the option I described, some files would end with
different numeric ids than they should. In particular, the knoppix cd has
different values for cups and other system accounts, and when restoring
the files would use those values.

When booting the restored system, those files would have invalid

Not as such. As tar uncompresses using user and group names (in _my_
experience), the extracted files will be usable by the users on that

Of course, if you consider the "use" of such backup as above, then it
still is a problem.
