I first noticed that the installation script ran to completion and that
the VM seems to stop properly.  Then I saw our code that did:

  (zero? (marionette-eval '(system #$script) marionette))

So I just tried adding:

  (pk (marionette-eval '(system "/run/current-system/profile/sbin/reboot")
                       marionette))

to the ‘basic’ test.  I noticed it would return 15, and then I got it.

Nothing fancy, mostly stubbornness and perseverance.  :-)
