Changing /etc underneath is the thing that is already implemented
by /etc/rc.d/bootconf.sh. But there are a couple of steps in front
of it.

Magic symlinks can do this earlier and work automatically. I use it
to boot the same system either as MACHINE=amiga or MACHINE=virt68k,
which requires specific fstab files and /dev directories.


But neither really helps if you want a shared root, that, ideally,
would require to be read-only and you need a solution for the
writable parts outside of /etc.

Supporting machine-specific kernels and other standalone code also
needs extra handling. But for network boot that's might already
be there.
