FWIW, I have separate /usr on several systems, and haven't needed an initramfs
thus far.  I thought we had some trick active in busybox or even eudev that
handles separate /usr for *simple* filesystem configurations (i.e., just basic
partitions, no LVM, evms, encryption, etc).

So I don't there would be immediate breakage in this scenario.  It's going to
depend on how a given system was configured.  Simple setups appear to
JustWork(), AFAICT.
