Just a reminder so people don’t run away ;-): the upgrade story got much
better shortly before 0.15.0, when ‘guix pull’ got the ability to “build
Guix from Guix” in a way that does not rely* on the currently installed
Guix.  For example, you can run 0.15’s ‘guix pull’ and upgrade to
today’s Guix without problems.

* More specifically, ‘guix pull’ relies on a small subset of Guix
  functionality that hasn’t changed in a couple of years, which is a lot
  given Guix’s history.
