There are currently three utilities provided to save your boot configuration
changes to the boot partition: ybin, mkofboot, and
yabootconfig. Ybin copies yaboot,
yaboot.conf, and the CHRP script to the boot partition, and then
performs the necessary blessing. Mkofboot initializes the bootstrap partition,
then runs ybin. And yabootconfig creates a working
yaboot.conf and then runs mkofboot. For details and
options of these utilities, see the associated man pages or type the utility
name followed by --help on the command line.
