Dynamic linking is probably going to be the killer piece. After every
update, you'd need to make sure all the libraries the binary needs are
also accessible on the / mount.
The other piece is probably somewhere along the lines of "if you're
going to use an initramfs anyway, now you can put / on
$composite_block_device, too!" (Which is something I'll probably start
doing on any system where I'd want /usr on a composite block device
anyway. Which is pretty much all of them; I like the load consumer
balancing behaviors I get from RAID{0|5|6})
