My standard update sequence involves booting the new kernel multiuser, then shutting down to single user. I do that because the test box that I always install on first mounts the source and object trees via nfs, and that's the easiest way to get them mounted. I then run installworld and mergemaster in single-user mode, and reboot yet again to make sure everything is going to be fine. Even after doing all that on the test box, I still reboot to single user after doing installkernel on everything else, as not all the systems use the same drivers, so that particular kernel needs to be checked. <mike -- Mike Meyer <mwm@mired.org> http://www.mired.org/home/mwm/ Independent WWW/Perforce/FreeBSD/Unix consultant, email for more information.
