It seems ext4 is being created by default with 64bit and metadata_csum
features since stretch beta 6 d-i release. A separate /boot partition
formatted as ext3 would be a solution; as it was for some time before
yaboot got support for ext4.

Instead of doing separate /boot we might be better off to adjust
newworld partition recipe to accommodate grub installation while
disabling d-i 64bit and metadata_csum features on powerpc to allow for
installation of yaboot.[0] Once we transition to grub we can get rid of
yaboot-installer together with ext4 feature limitations. Mathieu is
volunteering to do some work in this regard.[1]
