When a device with a UUID is missing, canonicalize-device-spec will throw an
error. This error is not handled for mount-may-fail? devices. That means
that if you use UUID device and it isn't available, the boot will hang on
the user-file-systems not being started. All user services depend on that
service.
Also added a test for this behavior.
* gnu/build/file-systems.scm
(mount-file-system): Guard canonicalize-device-spec call.
(canonicalize-device-spec): Throw &partition-lookup-error on missing
partition.
(&partition-lookup-error): New variable.
* gnu/tests/base.scm (%test-missing-file-system): New variable.
