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?
