That's really odd. I made it use the partitioning recipes for powerpc and it should
have matched to this recipe [1] on your machine which clearly contains an ext2
partition for /boot.

What do you mean with "in the past"? Which installation image?
Please note that our reference is the powerpc NETINST installation ISO.

Ok, good.

Please ignore this for now and let's only focus on the proper partitioning.

Yes, can you please test this? Apparently, the /boot partition is not always required,
see the reference to [2] below.

When was that machine installed?
In this context, I just found this commit [2] which added the /boot partition. Note the
additional "$defaultignore{}" designation which apparently means the partition is not
created in all cases.

Again, please write that down and let's resolve that later. It's very easy to change
the partition sizes and we can do that. However, it's more important to get the
basic partitioning fixed first.
