How well does the distro integration work? Eg. if I change something in /etc/default/grub and then run grub2-mkconfig, can I expect my changes to be picked up? In which scenarios will that *not* work? > Using Linux for a boot loader is not powerpc-only thing really, some > folks do this too (forgot who, just heard this at the KVM forum). While other options are available and some architectures use something else entirely, GRUB is the de-facto standard across most of the non-obscure architectures. I guess the question is whether it's more important to be consistent within the architecture or across them. I think the latter might be preferable, especially when we consider what I think is the most common scenario, that is, someone who's used to having GRUB on their x86 machine running a ppc64 guest on the cloud. The more skills they can automatically transfer over, the better. > > Personally I quite like the fact > > that I can use the same bootloader across x86, ppc64 and aarch64. > > I am not suggesting removing SLOF soon Perhaps the patch subject shouldn't be "kill SLOF" then? ;) -- Andrea Bolognani / Red Hat / Virtualization
