I mean, what does the old kernel > have to do with old utilities being used to build the new kernel? No. It means if you CVSup'ed your source _after_ building a kernel, only the buildkernel method uses the new binaries in /usr/obj to generate the kernel. Other methods will build the kernel with userland binaries, which will be out of sync with the sources after make buildworld. > In that case, would the following sequence be correct? > o make buildworld > o make buildkernel > o make installkernel > o make installworld > o reboot > > Basically, is it safe to do "make buildkernel" before "make > installworld", ie with the old userland?

It is unsafe to build a kernel before you build a world in your object directory (usually /usr/obj).
