Why doesn't motd show up when I su to root?
When I do sudo -i isn't that like creating a root login shell session? Why isn't motd displayed? motd=message of the day.

I think I answered it myself, it is only called for remote login sessions, once you're connected, subsequent shells only read /etc/profile.d and ~/bashrc etc... Is that correct?

"luxadm display" seems very appropriate, but requires root access.
Is there anyway I can get the FC path information?
