Build your OS on the easy-to-get-to machine, burn a bootable CD containing the stuff you need, make damn sure it does what you want it to (I specified identical, didn't I?), and mail it to the co-lo facility with instructions to insert and boot it when you call and tell them to. When you'ready, you log in and shut the machine down hard and make the phone call. If it fails, you go back to the old system, possibly by having the co-lo folks reboot with the previous CD. If you don't need to do database stuff, you may be able to make a system that will run at a high securelevel. It is conceivable that you could run entirely off the CD. -- Mike Andrews mikea@mikea.ath.cx Tired old sysadmin since 1964 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
