Oh, man, I think it's time to modify the manpage as -- at least to me
-- what you said wasn't obvious:
OPTIONS
-u user[:group]
setuidgid. Set uid and gid to the user's uid and
gid. If user
is followed by a colon and a group, set the gid to
group's gid
instead of user's gid. All supplementary groups are
removed.
-U user[:group]
envuidgid. Set the environment variables $UID and
$GID to the
user's uid and gid. If user is followed by a colon
and a group,
set $GID to the group's gid instead of user's gid.
So the difference is that -u drops privileges before the program is
invoked and -U after?
Thanks for your help. Next step: tinydns.
