Correct, bulding things doesn't influence anything actually running. You have one thing wrong in the above for the shared build: don't specify KERNCONF on the command line, set it in /etc/make.conf. On the master, /etc/make.conf has "KERNCONF=MASTER SLAVE". On the slave, it's "KERNCONF=SLAVE". There are now three steps: 1) On the master: # make buildworld # make buildkernel 2) On the master: # make installkernel # shutdown -r now # and come up single user # make installworld # mergemaster # reboot 3) On the slave: # make isntall kernel # shutdown -r now # go multiuser # shutdown now # and then single # make installworld # mergemastger # reboot Step 1 *must* happen first. The difference between step 2 and 3 is that you need to mount the network file systems on the slave. If bringing it all the way up is a problem, you'll have to do those things by hand. Step 2 and 3 can happen in any order. I typically do the slave first, as it's a test system, and if things screw up there's no immediate need to get it back up. I don't see much need for doing the installworld & mergemaster multi-user. It takes about 15 minutes from initial shutdown to new prompt, including doing a level 9 dump after while it's down. <mike -- Mike Meyer <mwm@mired.org> http://www.mired.org/home/mwm/ Q: How do you make the gods laugh?
