    file-systems: Always wait for devices to show up.
    
    Previously, 'canonicalize-device-spec' would wait for devices when they
    were specified as a label or UUID, but would not wait when the user
    passed a "/dev" file name directly.  This could cause problems when
    the /dev node takes a while to show up.
    
    * gnu/build/file-systems.scm (canonicalize-device-spec): Add 'resolve'
    call in the 'string?' case.
