[PATCH v2 5/5] Perform GRUB installation for newworld targets and configure auto boot
This patch requires the nvram tool which is part of the
powerpc-ibm-utils package.
v1 -> v2:
- adapted changelog entry and shrinked commit message
- added help messages for manual setting of NVRAM vars if automatic
setting fails
- configure NVRAM to automatically boot the machine
- failure of unmounting and mounting of the OFFS (NewWorld bootstrap
partition) before and after the CHRP boot script is made bootable
from OpenFirmware is now fatal for the GRUB installation

* Detect and select newworld bootstrap partitions
* Handle HFS file systems (format, mount, unmount, fstab entry)
* Patch the CHRP boot script
