The ISO Rock Ridge extensions already have the ability to make a symlink
whoose components can expand to the hostname or the mountpoint (why did
they include hostname and not host type?). So here's a hack: make the
default hostname of the kernel the arch type, then have symlinks in the
cdrom root with the hostname component in them and pointing to the right
arch dirs, the use that to union-mount things in the right places before
changing the hostname. Ugly -- not sure this is even close to the best
way to do it for real -- but it would work. personally, having the
kernel try init.<arch> first seems like the cleanest solution for those
who don't want something fancier like AFS @components or CDFs (and most
people seem to be violently opposed to them).
