We don't add the domain ourselves; the resolver does that. (iirc, we do
or did allow for unambiguous abbreviations, though, which may be
confusing.) I was thinking:
$ test -d /afs/.git
1. Look up 'git' in csdb -> no match
2. See that 'git' has no dots in it, and fail immediately.
Or if an entry does exist:
$ test -d /afs/.git
1. Look up 'git' in csdb -> match, but no servers
2. Look up _afs3-vlserver._udp.git (no trailing dot) -> success for cell
'git.example.com'.
For an FQDN:
$ test -d /afs/cell.example.com
1. Look up cell.example.com in csdb -> no match
2. See that cell.example.com has a dot in it, so do not fail.
3. Look up _afs3-vlserver._udp.cell.example.com. (trailing dot) -> success
