from gnu/system/vm.scm it is seen that our "/tmp" mount is filtered out and
replaced with a "/tmp" file-system that is mounted with (needed-for-boot? #t).
This last bit is crucial as the problem was caused by the user specified "/tmp"
file-system lacking this part which caused "/tmp" being mounted after
x11-socket-directory-service has run, effectively shadowing the directory.

[1]: &lt;https://issues.guix.gnu.org/57589&gt;

* gnu/tests/gdm.scm (%test-gdm-wayland-tmpfs): Delete variable.
(make-os): Remove tmpfs? argument.
(run-gdm-test): Remove tmpfs? argument. Add a small delay since
waiting for gdm.pid is not enough, causing the tests to fail sporadically.
