Users and groups kept after a port deinstallation
in [Ports]
|
From: David DEMELIER on 21 May 2010 06:11 Hi, I used pkgsrc for a while on NetBSD. I was used to the pkgsrc notifications about the users and groups leaves, when some ports are removed these leaves are not used anymore. e.g pulseaudio needs some users on the system. Then the pkgsrc framework says to the user that are some users not used anymore and they could remove them safely. Ports has the lack of this kind of notification, that's why I would start writing a patch in the ports infrastructure, or maybe someone already proposed something else ? I apologize for my bad english. King regards. -- Demelier David _______________________________________________ freebsd-ports(a)freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-ports To unsubscribe, send any mail to "freebsd-ports-unsubscribe(a)freebsd.org"

This was discussed in the following bug-report: http://www.freebsd.org/cgi/query-pr.cgi?pr=108514 I think the proper solution is to create a +UGIDS file to be able to maintain a refcount, but the status quo isn't that bad. -- Florent Thoumie flz(a)FreeBSD.org FreeBSD Committer _______________________________________________ freebsd-ports(a)freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-ports To unsubscribe, send any mail to "freebsd-ports-unsubscribe(a)freebsd.org"

Personally I'd much prefer to keep them so ls -l, filemanagers etc can continue to use names rather than numbers for any files left behind. IMO the status quo is better than any solution that involves automated deletion. _______________________________________________ freebsd-ports(a)freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-ports To unsubscribe, send any mail to "freebsd-ports-unsubscribe(a)freebsd.org"

I agree by and large with RW, but it would be nice if there was an audit tool to do this check and suggest whether or not a group should be added or removed in general, regardless of whether or not a pkg/port was added or removed.

Having unused logins on a system is bad! and just for the case of mapping to uid/gid does not justify leaving them. uid & gid printed in ls(1) output may be ugly as well but you can not log in with one of those and they should be handled in a way that is prompt to login removal. find / -nouser find / -nogroup and then after inspection add -delete -print. find / -empty Of course these can be combined to form a simple one line command but I will leave that as a exercise for the reader.
