    Comment out initgroups from example nsswitch.conf (Bug 25146)
    
    In commit 4b7c74179c8928d971d370e1137d202f891a4cf5 the nsswitch.conf
    file was harmonized with downstream distributions, but this change
    included adding "initgroups: files". We should not add initgroups by
    default, we can have it, but it should be commented out to allow it
    to inherit the settings for group. The problem is principally that
    downstream authconfig won't update initgroups and it will get out of
    sync with the setting for group.
