As Allan Jude pointed out earlier in the thread, it's a lot easier than that: just set the "kernels" variable in /boot/loader.conf. For example, I update, build, boot, and run FreeBSD on my laptop daily. That process installs /boot/kernel (after moving the previous one to /boot/kernel.old). I like to keep a "recent known-working" kernel around that isn't automagically replaced, so: g1-252(11.1-S) grep kernel /boot/loader.conf # Experiment to see if kernel.save can be an option from the boot menu kernels="kernel kernel.old kernel.save" g1-252(11.1-S) (And yes, it does work -- verified empirically.)
