I'm hoping someone will sanity check the following as a reasonable course of action, as I really don't want to mess anything up. I'm reading: http://www.freebsd.org/doc/en/articles/problem-reports/index.html The problem is the man page for renice. Has anyone tried it as the root user in a jail? You can increase the nice value of any process within the jail you like, but you can't decrease it. In other words it behaves as though you were a standard user except you can change other users' processes too. This all seems reasonable as you don't want the root user in their jailed machine pinching CPU time from everyone else. It's probably documented somewhere, but I've only found an old discussion about allowing jailed users to renice anything. It's certinaly not in the first place I'd look - the man page. So, what I've done: I've searched for "renice" in http://www.freebsd.org/cgi/query-pr-summary.cgi?query and not found it listed. I've Googled for things like "renice in jail" I've checked out the behaviour out on running systems I have available to me. I'm about to fill out this form here: http://www.freebsd.org/send-pr.html Should I do anything else first? Thanks, Frank.
