For this, you will notice new /etc/pam.d/mock, /etc/consolehelper/mock files which configure mock. The default config is set up to operate exactly the same as the old 0.8 branch: ie. you must be a member of the 'mock' group to run mock. Additionally, with consolehelper comes one new feature: if you are not in the 'mock' group, you will be prompted to enter the root password and it will run. This means you can run mock without worrying about any pre-setup.

Hey all

    Did I hit a bug here or am I doing something very stupid ? According 
to the paragraph above, I should either be allowed to build as user, or 
be asked for the root password. Helas....
