If the user owns files that aren't removed until purge time, that would
leave dangling files that may end up owned by an unrelated service user when
the uid is reused, which would be a bad thing. (This is also why it's
generally a bad idea to delete system users at all in maintainer scripts,
because you can't always know that there are no files left owned by the
user.)
Since this package creates a /var/lib/nut directory which may be full of
files owned by this user, and does nothing on removal to clean up these
well, there shouldn't be anything left. This is just for socket
communication, and pid files. So I'll also there care of this one.
files, I think it's best to just not delete the user at all.
If there is no objection, we'll go that way.
thanks to you both.
