Hi.. It was a good explanation. What is the use of wheel ? where it is used?

[johnreid]

So in Linux is there a way to add a group as a member of another group (nested groups)? For instance if I recall correctly on Solaris/SunOS a NIS+ group could be added to the membership list of a group in /etc/group as @nameofnisgroup and NIS+ itself had nested groups. However a local group defined in /etc/group could not be made a member of another local group.

Interestingly the uni that I used to work at hacked SunOS to allow nested local groups.

Still trying to understand what group password is useful.
