For initial installation on a machine, you can use yabootconfig to
first create a yaboot.conf file and then install everything on
your bootstrap partition. Yabootconfig reads the running system's
/etc/fstab to determine the kernel location, and detects the
location of the 800k Apple_Bootstrap partition. The Debian installer uses
yabootconfig behind the scenes in the Make Hard Disk Bootable
step.
Normally, the initial boot configuration is created while in a ramdisk
installer environment, with the system being installed being mounted under
/target or /mnt. To run yabootconfig
under these conditions, supply the path to the target system with -t or
--chroot option. For example: yabootconfig --chroot /target
The yaboot.conf automatically created by yabootconfig
will just control booting of the linux system under which it was created. To
boot additional OS's or add other options, you will need to edit the
yaboot.conf file.
