CentOS 7 supports several architectures: - x86-64 - aarch64 - ppc64le - armhfp - i386 - ppc64 - power9 All except 'x86-64' are stored in /altarch/7/ directory on mirror.centos.org and are mirrored only by subset of mirrors. RHEL 8 treats aarch64, ppc64le, s390x, x86-64 as equals - package has to build on each of them to get included in repositories etc. So the question is how CentOS 8 will be organized? Moving everything into mirrors.centos.org/centos/8/ will simplify live for all of those using non-x86 machines as repos will be widely mirrored and there will be no need of handling centos|altarch in external projects. I think that /altarch/8/ may exist for armhfp, i386, etc architectures which are not a part of RHEL 8. What do you think?
