Yes, the project has these resources. But a kernel porter will of
course need to install and test new kernels. Does the porterbox provide
nested virtualisation for any developer? (For some reason we haven't
enabled KVM_BOOK3S_64, which I think means the answer is currently 'no',
but we can fix that part, leaving the administrative issue of
permissions to use KVM.)
How about other PowerPC hardware, in particular 32-bit machines? How,
if at all, would a new kernel porter support these?
