Comment 13 for bug 1872941

Unfortunately installer-arch/ is hardcoded portion of the prefix in the internal archive publishing, internal mirroring, and external mirroring, thus I cannot change it to legacy-installer-arch.

Also these will only exist for a short period of time until June, so I don't see the point of investing into redoing all of our archive publishing to support this.

If you use an internal mirror, you can modify it with extra symlinks to symlink legacy-images to images to fix your internal deployment. However, we should work together on moving away your virt-install deployments away from d-i.
