Re: su and passwd
Hi you can use passwd root, after su, or use su - that simulate a full login and the command passwd.

This is the traditional behavior of su Running su -l works good. Why if user ID is == 0 or if there's no -l, the $USER will not be set? What is the policy? I've tried this also on OpenBSD 4.9 with same result. Thanks in advance. Alessandro.

Re: su and passwd
LOL, when I started on OpenBSD, I created a bug report about this. Dev want it this way, the're must be a reason to it but since it's not standard, the must also expect question like this. A answer why it's this way would be fine so user asking about this could be refered to this answer.
