No; you should be using sysctl to get at the information. > I'd be willing to add this code if so.. it's not much. > > Unrelated question: SYSINIT() doesn't work from KLD modules. > Is this problem being addressed? It does; it's critical to the functioning of KLD modules in general. -- \\ Sometimes you're ahead, \\ Mike Smith \\ sometimes you're behind. \\ m...@smith.net.au \\ The race is long, and in the \\ msm...@freebsd.org \\ end it's only with yourself. \\ msm...@cdrom.com To Unsubscribe: send mail to majord...@freebsd.org with "unsubscribe freebsd-current" in the body of the message
