   It would be nice to have some way before the installkernel, I think, to make sure
the installworld will succeed before installing kernel or world. Failure of the latter to
install has often caused nearly-unfixable problems here. [ luckily, 'nearly.' ] ... Perhaps
using some no-fail mountpoint or jail or chroot destination?
