(HANDBOOK) Note: You do not have to be in SUM to install the world and/or the kernel. You can install them just fine in multi-user mode. I do this all the time on remote system, as dropping to SUM would knock off the SSH connection. All you have to do is make sure no one else is logged in, stop as many services and daemons as possible, then do the installworld, and reboot. It's not recommended in the Handbook, but it's not forbidden either. > So that is way, they both need to be installed in SUM, in one shot! Kernel > then world! Or ... they can be installed in MUM without issue. > DO YOU KNOW, what to look for, in sys that will indicate to my function, > that it is in SUM? No network configured, no daemons running, just a single shell running. IOW, everything can be done manually in MUM to "simulate" SUM. -- Freddie Cash fjwcash@gmail.com
