Always read /usr/src/UPDATING and the stable list first. eg some net cards now need miibus. (I'm assuming that you don't have serial console access to these boxes.) As other folk have said the official instructions (from /usr/src/UPDATING) are make buildworld make buildkernel KERNCONF=YOUR_KERNEL_HERE make installkernel KERNCONF=YOUR_KERNEL_HERE reboot (in single user) make installworld mergemaster reboot If you are remote you don't have any way to select single user mode and start the network services. hacks > /dev/null :) You have a number of choices depending on how remote these boxes are. Go to the machine and work from the console (safe). Go to the machine and configure a serial console (complex) Skip the reboot step and cross your fingers (mostly safe) Reboot multi-user and cross fingers and toes (not recomended) If you decide to reboot you should be aware that having a new kernel with an old world can break network services. If the boxes really are remote then get a local box with identical hardware and practice the remote install on that box. Another useful tip. If these boxes are on your LAN then you don't need to build the software on each system. Build kernel and world on one machine and nfs export (ro) /usr/src and /usr/obj. Run installkernel installworld and mergemaster from the nfs mounted /usr/src. There are gotcha's with this of course. The mount points should be the same, as should the contents of /etc/make.conf. Don't set any special CPU options. Don't reboot if you do this. Having mount_nfs fail on you is stressful - I speak from experience. This is what I do, and I've yet to have any major problems - pilot error excepted :).
