    hurd-boot: Support system init: Create essential device nodes.
    
    * gnu/build/hurd-boot.scm (make-hurd-device-nodes): Cater for existing
    directories (dev, servers).
    (set-hurd-device-translators): Remove /servers/socket/1, that is created by
    libexec/console-run.  Cater for nonexistent /dev/console.
    (boot-hurd-system): Call make-hurd-device-nodes on initial run.
