If you only boot into single-user mode (so you're not running all the daemons), then what programs would not work? So far I have never run into any problems. I should admit I'm generally less than a month "out-of-date" when I do a new buildworld, so not all that much has changed. I know that programs like 'ps' or 'top' will produce the wrong results, of course, but I would not expect any catastrophic problems should happen. Much more important, to me, is to catch the cases where the new kernel does *not* work, and I definitely have run into those cases. When a problem like that happens, at the time I find out about the it, the only change I have made is to install the new kernel. At that point it is pretty easy to back out of the problem. If I do the installworld before booting up off a new kernel, then I would definitely be in trouble when I realize the new kernel does not work on my hardware. -- Garance Alistair Drosehn = gad@gilead.netel.rpi.edu Senior Systems Programmer or gad@freebsd.org Rensselaer Polytechnic Institute or drosih@rpi.edu To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
