assignment of UIDs

[chris at umcp-cs.UUCP]

Yes, all-numeric login names are not good since all system utilities
tend to look to see if an argument is all digits, and if so, doesn't
do a login name lookup.  Useful for bringing up a system with a
scrogged /etc/passwd, maybe.

Getty ignores all-numeric names because they have neither an uppercase
letter nor a lowercase letter.  That's a bug in getty.
