Hi Mark,

You probably need to modify the ofboot.b file in the bootloader partition
to add another OS option.  Actually, you probably need to edit the
/usr/lib/yaboot/ofboot script which ybin uses to generate the ofboot.b
file.  Otherwise, if you ever reran ybin, it would clobber the ofboot.b
file in the bootloader partition.
