Seems like a great idea *after* the system is fully running (or the
root partition is at least mounted).

Seems like overkill to boot most systems.

As I understand it, all that should need to go into the initramfs is
enough to mount the root partition. Normally, this would probably be
a handful of drivers that are unconditionally known to be needed. So
why go through several user-mode programs to make a decision that can
be made once and built in?
