Having done the complete install (including the workaround steps) yesterday, and not wanting to spend the time to do it all again, I booted into rescue mode and executes a shell in the /target system.
I had to manually mount /boot/grub from /dev/sa2 because the rescue mode didn't do it automatically. Then to get the information Adrian wanted, I executed the following script # df -TP Filesystem Type 1024-blocks Used Available Capacity Mounted on /dev/kmac/root ext4 19092136 1156780 16942488 7% / devtmpfs devtmpfs 1881600 0 1881600 0% /dev tmpfs tmpfs 406656 1664 404992 1% /run /dev/sda3 ext2 242093 64566 165028 29% /boot /dev/sda2 hfs 124990 6510 118480 6% /boot/grub # ofpathname /dev/sda2 /ht@0,f2000000/pci@5/k2-sata-root@c/@-1/@0:2 # nvram --print-config=boot-device /ht@0,f2000000/pci@5/k2-sata-root@c/@-1/@0:2,\grub # grub-install --macppc-directory=/boot/grub Installing for powerpc-ieee1275 platform.

Hope it helps! Rick
