 It used to, but only "if [ ! -f /tmp/.world_done ]", and you were
 way beyond that point, was it release.9?  Nevertheless, I'm not
 going to repeat all arguments explaining why "make world" in
 CHROOTDIR is an etremely bad idea.
 
 In older days, it was necessary to ALWAYS upgrade to a recent
 before attempting to "make release".  These requirements are
 now lifted, and it's often that you can build a fresh snap on
 an older system.
