The actual bug was reported here: https://bugs.debian.org/882076 The other grub-related powerpc issues can be found from: https://udd.debian.org/cgi-bin/bts-usertags.cgi?tag=powerpc&user=debian-powerpc%40lists.debian.org > Example: your /boot UUID is 12345678-abcd-ef01-1234-abcdef012345, > grub.cfg on the HFS partition together with core.elf from GRUB2, blessed > (:tbxi) using hattrib: > > search --no-floppy --fs-uuid --set=root > 12345678-abcd-ef01-1234-abcdef012345 > > set prefix=($root)/boot/grub > > configfile /boot/grub/grub.cfg > > This will load grub.cfg from the real /boot partition and continue from > there, no need to get the ofpath. > > At least that was how I did it on a Power Mac G4. > > > Linux User #330250 >
