YMMV ;-) In maybe most cases it would work, but in others don't. I remembered at least two situations where single-user was really necessary (elf branding changes between 4.0 and 4.1, and some other, don't quite remember, where kernel and userland become incompatible). As someone already mentioned, serial console would be of great help for remote upgrades. And for remote troubleshooting, too. ;-) I would also recommend you getting "server-like" MBs with ability to redirect BIOS output to serial port -- but it's kind of being "perfect in everything" ;-) Sincerely, D.Marck [DM5020, DM268-RIPE, DM3-RIPN] ------------------------------------------------------------------------ *** Dmitry Morozovsky --- D.Marck --- Wild Woozle --- marck@rinet.ru *** ------------------------------------------------------------------------ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
