Yes: you need to have ‘installation-os-for-gui-tests’ (or preferably a
variant thereof) include all the services/packages needed for the target
config.

In the manual installation tests we use ‘define-os-with-source’ to both
embed the target OS and its references in the installation image *and*
have the source of the target OS available in /etc/target-config.scm in
the installation image.

The 2nd step is not relevant here, but the first step remains necessary.

It’d be IMO clearer, although technically equivalent, to make it:

  (or (marionette-eval exp marionette)
      (throw 'marionette-eval-failure 'exp))

Perhaps you don’t even need to catch it.

Thanks for working on this!
