When using `--vm-test` in combination with `mirroredBoots`,
it is necessary to configure `boot.loader.grub.devices` as an empty list by setting `boot.loader.grub.devices = lib.mkForce [];`.
This adjustment is crucial because the `--vm-test` mechanism automatically overrides the grub boot devices as part of the virtual machine test.
