Good point.  I've added:
   * Better support for read-only (or read-mostly) boot disks (esp, etc
     & var -- also see zeroconf & consider run-time configuration like
     dhcp, named.conf, etc.)

   * Separation of configuration data and system image (kernel/binaries)

I'm thinking that the build-to-image would help here because a lot of
the configuration should be in there.  So I've added the following
points under there:
      * Easy generation of new, custom platforms with little to no
	duplication of code/configuration
      * Easy maintenance of platforms (easy to upgrade from, say,
	5.1 to 7.2, maybe from 5.99.x to 6.0)
