What about
* the FHS?
* "#! /bin/sh" in thousands of existing scripts?

If anything, wouldn't it make more sense to move stuff in the opposite
direction, from /usr/bin to /bin ?  "usr" doesn't really mean anything
- originally it was used because the filesystem format couldn't
support more than 64MB(?) in a single volume, so the system had to be
split to / and /usr.

Also, Fedora already sort-of has a system for stateless OS images -
see /etc/sysconfig/readonly-root.  What will happen to it?

And more importantly, what is the overall benefit to our users?  I
can't find anything compelling in the "Benefit to Fedora" section (if
/usr/ can be snapshotted, why not / ?); AFAICT this requires changing
257 packages for mostly aesthetic reasons.
