Restricting Use of su
Currently the section on this page titled Use su includes these two sentences:

"Some systems require that you join the wheel group to have access to su. The requirement is that your username be listed in /etc/group on the line for group 'wheel', group id zero. This requirement does not exist on some systems."

It seems reasonable to me to include a few sentences on how to create this requirement. Perhaps something like:

"One way to enact this requirement is to modify the file permissions on to only allow members of group 'wheel' to execute it. For example, my SUSE 10 installation originally had these permissions: -rwsr-xr-x 1 root root I changed them to: -rwsr-xr-- 1 root wheel" --Jarsyl 08:59, 1 February 2007 (UTC)
