I think on linux (most systems I ran into actually), UIDs and GIDs are
numerical with just a "human friendly" translation (from passwd/group.
If you extract a tar file, for example, and the owner/group
(numerically) does not exist on the target system, you get to see the
'old' uid/gid from the src system.

Does anyone understand why there exists a "--numeric-owner" flag? I replied
off-list with the same information as others posted here, but the existence and docs for
that flag at least imply that the default is usernames, not UIDs.
