Is there some > problem with username == primary group name? pam_umask requires both username == primary group name and uid == gid before it will assume UPG are in place when using its 'usergroups' option, and I am not willing to diverge from upstream on this as this would mean admins coming from other systems may get an unpleasant surprise when they find that Debian gives a more relaxed umask than they were expecting in some corner cases. So either someone should convince Linux-PAM upstream to change the behavior of pam_umask, or adduser should enforce the same rules as other implementations, if pam_umask is to be involved here. Beyond that, I have no particular opinion on this question. Cheers, -- Steve Langasek Give me a lever long enough and a Free OS Debian Developer to set it on, and I can move the world.
