I'd object to this because we already have an MI way to do it: have the
boot loader load miniroot.kmod.

It's not hard to implement support for that in non-x86 boot loaders. I
outlined the needed changes on tech-kern a couple of months ago.

Agree. Ramdisks are a great tool but they suck for automated/assisted
installs. Maintaining them wastes lots of our time and places restrictions
on what the installer can do.
