I name them for the short name used in /etc/hosts and I can "buildkernel KERNCONF=CORAL" on RUBY and do the installkernel and installworld on CORAL. If you have all 3 config files on ruby, you can add "KERNCONF=RUBY GENERIC CORAL" to ruby's /etc/make.conf, all 3 will be built on ruby. Since RUBY is 1st, a "make kernel" will build all 3 but install RUBY. > > If you don't have machines of completely different architectures, you > can buildworld once, then mount /usr/obj and /usr/src as many times > as you want and install the same userland/kernel to a lot of > machines. I have modified a computer and mismounted 2 IDE drives when I was reassemblying it. There were links that were apparently broken. I swapped them back but still couldn't do a builds after that. So, I just mounted the the 2 file systems from a running system and did the installs. I could do builds once more. I think I needed 15-20 minutes from the time I figured out what was wrong and had done the buildkernel for the sick computer to having a consistant running system. The installworld took a wee bit longer than the 4 minutes it usually takes but it worked.
