system: File system sources can be marked as labels or devices.
* gnu/system/file-systems.scm (<file-system>)[title]: New field. * gnu/services/base.scm (file-system-service): Add #:title parameter. In 'start' gexp, use 'canonicalize-device-spec' and honor TITLE. * gnu/system.scm (other-file-system-services, operating-system-root-file-system, operating-system-initrd-file): Adjust accordingly. * gnu/system/linux-initrd.scm (file-system->spec): Likewise. * gnu/system/vm.scm (system-disk-image): Add 'title' field for the root file system. * guix/build/linux-initrd.scm (mount-file-system): Expect the second element of SPEC to be the title. (boot-system)[root-mount-point?, root-fs-type]: Likewise. * gnu/services/dmd.scm (dmd-configuration-file): Select 'canonicalize-device-spec'.
