Build each Ubuntu media layout on disk and ask the resolver for its kernel and initrd: the netboot trees, the flat netboot layout, both casper images, and the POWER layouts where the kernel and the initrd sit in different directories. Pin the precedence the installer depends on, a netboot tree over a live image and a hardware-enablement kernel over the release one, and pin the three ways media resolve to nothing.
