Subject: [su] New su utility messes with my PATH
Date: Sat, 15 Sep 2012 15:17:27 +0200 [thread overview]
Message-ID: <50547FE7.204@archlinux.org> (raw)

I found what I think is absolutely unexpected behaviour in the new su
utility. It seems to have been introduced by commit a6fdd3f8.
It is about /sbin and /usr/sbin being in the path: Whenever you switch
to a non-root user, they are removed from the path, and when you switch
to root, they are added. I find it completely unexpected that su (when
not running with -l) messes with my environment at all.
Commands like
PATH=... su -c "cmd" user
do not work as expected.
In my opinion, when you wish your path (or anything in the environment)
to change you should a) use -l to start a login shell or b) configure
your scripts to take care of it.
I propose to revert the mentioned patch. Opinions?
