Hello, Sometimes I need to update some parts of the FreeBSD system in a way that requires me to be in single-user mode. For example, if I want to replace the libc, or if I want to keep my system current using CVSup and using "make world", etc. I know I can go to the console of the host and type init 1 to go into single-user mode, then I have a shell on the console, where I can issue the commands I need to issue to update my system, and then when I exit the shell with "^D" or "exit", the system goes back to multi-user mode, without the need to reboot. I would like to know if there's somehow a way to do this without the need to be on the console of the host. For example, I would like to know if there's a way to write a script and tell FreeBSD to go into single-user mode, execute the script, and get back to multi-user mode, without the need to be on the console. I have two reasons for that. One is that I have to manage many (30+) hosts with FreeBSD, and I would like to update all (or most) of them at the same time. Other reason is that I would like to be able to schedule this kind of update to 3:00AM or something like that, so that fewer people will be affected by the downtime of the host, and I would like to do this update without the need to be at the business to have to type the commands. Ok, I know this would probably be too dangerous to do without watching, but hey, if I test it before on a testing machine, I don't see much trouble in doing this... Hope you can help me with this...
