Fun with nosetuid!

 On an unpatched Centos 4.4 system I chmod'd /usr/bin/sudo to ug+s, and set the 
filesystem in /etc/fstab to defaults,nosetuid.  Reboot, and am told sudo needs 
to be set to setuid root. 

An ls -l shows rwsrws-- root root sudo 

I had to use a rescue CD to undo /etc/fstab for the filesystem partition so 
sudo would work. 

What am I missing?
