Sorry - I misunderstood your concern.

Yes, it gives the user permission to do whatever he wants (which isn't 
quite the same as the right to do whatever he wants - but the difference 
would take some explaining).  And yes, as I mentioned, the user could 
change the sudosh log files, and /etc/sudoers, and so on.

I generally take the view that if you can't trust the users with root 
privileges, you are in for a very difficult time - usually stated in the 
more absolute form "root can do anything", where anything includes erasing 
or replacing the o/s (though the reboot can be tricky over a network).  It 
might be over-simplistic as a view; it isn't too far removed from the 
truth.
