} My understanding from several PRs is that binary packages end up with
} numeric uids and gids wired into them, not names. Assuming this is
} actually true, it's a bug.
Hrmm, that's probably some app doing setuid([compile time
constant]). That's a bit of a pain and would require the person making
the package to generate a patch to make it call getpwnam().
