Nah, we don't really build static binaries, and /usr must be available
even in single user mode. IMHO /bin and /sbin are no longer useful.

Two comments:

This can be solved by making /media a tmpfs and require its subdirs to
be recreated on demand (as systemd does).

udev should never, ever mount stuff itself. This is dangerous and
explicitly not supported. Consider using systemd, udisks or another
daemon for this purpose. For more info about this, see the recent
discussion on the linux-hotplug mailinglist.

Thanks, that's an interesting read. Notice how a majority of his
concerns would go away if /bin, /sbin, /usr/sbin all pointed to
/usr/bin. That whole thread very clearly illustrates the challenges
the FHS faces.
