Note: This change requires an updated 'guix' package that contains
Linux-swap support in (gnu build file-systems).
* gnu/installer/parted.scm (user-partitions->configuration): Use UUIDs
in the 'swap-devices' field.
* gnu/installer/newt/final.scm (run-final-page)[wait-for-clients]: New
procedure. Use it.
* gnu/installer/tests.scm (choose-partitioning): Wait for
'starting-final-step' message and move configuration file dialog
handling to...
(conclude-installation): ... here. Send over PORT the reply
corresponding to 'starting-final-step'.
* gnu/tests/install.scm (gui-test-program): When ENCRYPTED? is false,
invoke 'swaplabel' in the marionette.
(installation-target-os-for-gui-tests): When ENCRYPTED? is false, except
a fixed UUID.
* gnu/installer/tests.scm (choose-services): Turn desktop-environments list
into a choose-desktop-environment procedure. This way, it is easier to select
all desktop-environments or none, in the same way as choose-network-service?
and choose-network-management-tool? arguments.
