Bug#990017: [REGRESSION] Bullseye CD installer images fail to install GRUB on OpenPOWER machines
Package: debian-cd
Severity: Grave
Attempting to use the latest Bullseye RC2 CD installer on an OpenPOWER machine results in a fatal error during bootloader installation:
Jun 17 21:14:45 grub-installer: info: Installing grub on '/dev/sda1'
Jun 17 21:14:45 grub-installer: info: grub-install does not support --no-floppy
Jun 17 21:14:45 grub-installer: info: Running chroot /target grub-install --force "/dev/sda1"
Jun 17 21:14:45 grub-installer: Installing for powerpc-ieee1275 platform.
Jun 17 21:14:57 grub-installer: grub-install: error: unknown filesystem.
Jun 17 21:14:57 grub-installer: error: Running 'grub-install --force "/dev/sda1"' failed.
The bootloader installs normally using the Buster CD installers on the same hardware.
