Changing this to an unprivileged user and adding it to mock group works
perfectly. Has anything changed lately ? Not having the unprivileged
user added to mock group, mock will ask for root password  but it will
fail to build anything:

You are attempting to run "mock" which requires administrative
privileges, but more information is needed in order to do so.
Authenticating as "root"
