I fixed all your remarks. But there's still an issue, the size of the
installation image is guessed badly in "run-install" for
"%test-gui-installed-desktop-os-encrypted"

--8<---------------cut here---------------start------------->8---
(image  (system-disk-image
         (operating-system-with-gc-roots
          os (list target))
         #:disk-image-size 'guess ;guess is too low.
         #:file-system-type
         installation-disk-image-file-system-type)))
--8<---------------cut here---------------end--------------->8---

applying the dirty snippet below fixes it, but you may have a better idea?
