I've had issues with both our ISO (yaboot powerpc) and official ISOs (grub ppc64 and grub powerpc).
Regarding our ISO, I think there is a mix between powerpc and ppc64:
- the ISO is powerpc
- the postinstall script sets up repositories for ppc64 (which are incompatible, unless one adds ppc64 as an additional platform. And even in that case, 64bit libraries do not get installed properly).
- the contrib and non-free repositories do not support powerpc/ppc64 platforms
- the fienix repositories are powerpc and our repository is ppc64 - I think they are not "compatible"
- There are updates that are kept back for good reasons. The postinstall script should not force update (using apt-get -y full-upgrade) as this might break the system.
About the official ISOs, powerpc or ppc64, I can boot and install the system, but grub doesn't install on my powermac G5 (already partitioned SSD). There's probably something bothering grub.
- Does anyone know how i could debug the grubinstall?
- I was able to use our repository with the ppc64 ISO (and install yaboot separately).
- powerpc behaves better than ppc64
- I don't think I have any hardware acceleration.
To summarize: it seems to me that we need separate powerpc/ppc64 postinstall scripts, to update apt sources.list, and install packages.
