From my own experience, anything I change in the GUI that requires authentication, it is for user 'chris' if that user was added as an admin with the checkbox in the create first user steps. If that checkbox is not checked, any authentication dialog that appears is for user 'root'.

My interpretation of Torvalds' complaint, is with the mere existence of authentication dialogs in the first place, for certain things. Mac OS X has always required authentication (from a user with "admin" privileges) for changing the Date/Time including time zones, which is an absurdity. In the most recent version, it's no longer possible for a non-authenticated user with admin privileges (in effect two levels of privileges for the same user with the same login and the same password) to install e.g. ICC color profiles to a folder making the profiles available to all users. So I'm an admin, and if I want to modify a folder, I have to enter my password in a pop-up authentication dialog to add/remove ICC profiles. Worse, the individual user folder for these profiles is now hidden by default. It's high order insanity.

As far as time zones and date/time settings are concerned, didn't there used to be a user-level setting for this? There's a variable for command line apps called TZ (for timezone) that can be set at the individual user's level, but apparently graphical applications don't obey this variable. I don't know about date/time itself, though.
For printers, currently installing printers does not require superuser privileges, but managing those printers installed by that user does. Is it possible to make it so that printers installed by that user can be managed by the user without superuser authentication?
