su: permission denied
help! i have just installed gentoo, and so far it beats the hell out of mandrake. however. when i type in su (or su root, or su - root, or su into another user i created to test with):
su: Permission denied
??? it is sorry? i know i have the right password, because i can log in normally as root. i created the user with:
# useradd my_name -m -G users,wheel,audio -s /bin/bash
btw wat is the group wheel for?
