Administrator group (80)

When creating accounts, Leopard sets the default group as 20 (staff) for both standard and administrator types. Is there any reason for the administrators not to be in group 80? Permission settings for many areas list the admin group specifically. If it isn't for administer privileges users, what is it for?

While the primary group id is now staff (20) this doesn't replace the admin group membership, which the admin users still have, rather it replaces the prior primary group membership of Tiger and Panther, which was the same as the short name and number. Thus, in Tiger I was user:francine (501) and group:francine (501). Now I am user:francine (501) group:staff (20), but I am also a member of admin (80). You check all your memberships in Terminal with the id command:

NoobiX:~ francine$ id
uid=501(francine) gid=20(staff) groups=20(staff),98(_lpadmin),80(admin),501(francine)

As you can see, I am actually a member of 4 groups.

Thanks, that clears it up. I lused the syntax: id and found I'm in a bunch of groups, including admin.
