It's a good thought - I have an O-Droid C1+ still on 7.1.2 booting
exactly that way.

The issue, though, is that the mue0 simply isn't in the device tree -
not yet. The kernel boots up, looks for mue0, doesn't find it, then
drops to a prompt. A few seconds later the USB bus stabilizes and mue0
attaches.

I assume attempting to use a USB key or USB-to-SATA device as root
would result in the same behavior.
