Hmm. on 'echo $USERNAME' I get root if I've logged in as root, even
while logged in as someone else with 'su', but nothing if I've logged in
as anyone else, unless I've done a 'su root' in which case I get 'root.
With 'echo $LOGNAME' I get the user currently logged in as, for example,
bob if I've typed 'su bob'.
I'd like it to catch any case of me being 'root', so I think I'm going
to stick with $USERNAME, perhaps later adding in a message to 'root'
somehow about such & such a user (determined by $LOGNAME) shutting down
as 'root'.
