I think that su needs your username to be in the list of members in
/etc/group, not just to have principal gid = 0 (which, if it is true,
is not in the su manpage, and therefore could be construed to be a bug.)
I could be wrong, but I'm going to try hacking on the su source
later on this evening. If I confirm this puzzling behavior I'll send-pr it.
