My conclusion that it is supposed to be hfs is based on the ybin man page:
"Ybin requires that the bootstrap(8) partition have an HFS or MSDOS
filesystem already on it."
Furthermore, hcopy's purpose is to copy files to and from an HFS file
system.
It might be helpful to read the ybin (and perhaps hcopy) man pages to
help you understand what might be going wrong. If it were me I would 1)
Make sure that /dev/hda15 isn't mounted 2) Read the man page for
mkofboot, and then try using /usr/sbin/mkofboot, which should fix the
partition format if it is jacked up. 3) If all else fails, send mail to
YDL and see if they respond. :)
