Implementation wouldn't be probably too hard, but I can't agree it should be committed. We need to know where jail's virtualization ends and I think it is too far. Of course it will be cool to have those sysctl on per-jail basics, as well as others from security.bsd. tree (like security.bsd.suser_enabled), but I'm not sure this is the right way to go. Any other opinions? If someone convince me we should do it, I can do it. -- Pawel Jakub Dawidek http://www.FreeBSD.org pjd@FreeBSD.org http://garage.freebsd.pl FreeBSD committer Am I Evil? Yes, I Am!
