[conclusion] root can't sudo

[T o n g <mlist4suntong@yahoo.com>]

My bad. 

The failed environment is a linux-live environment that I built myself. 
When mirroring it to HD, everything works fine. So it's actually the live 
environment's problem, not sudo's.

Thanks again for your comprehensive tips, which I'll garter bellow in 
case someone else need to troubleshoot:

- Make sure the 'root ALL=(ALL) ALL' line is in /etc/sudoers

% grep ^root /etc/sudoers
root ALL=(ALL) ALL

- should not have the "!root_sudo" option set

$ sudo cat /etc/sudoers | grep root_sudo || echo no 
no

Also check,
