The new boot blocks, installed by
disklabel -B $DRIVE
do handle (both a.out and) ELF kernels, despite looking very similar
to the old a.out-only ones. The idea is to provide a fallback
means of booting a kernel in either format.
So using a /boot.config statement like the above (or hitting any
key before seeing the /boot/loader prompt, to get the old "boot:"
prompt instead), is a recommended workaround for any temporary
/boot/loader problems.
