    hurd-boot: Use 'setxattr' instead of invoking settrans.
    
    Note: Using `getxattr' on the Hurd instead of running showtrans does not
    work (yet?).
    
    * gnu/build/hurd-boot.scm (setup-translator): Use 'setxattr' instead of
    invoking settrans.
    * gnu/system.scm (hurd-multiboot-modules): Add --x-xattr-translator-records 
to
    enable xattr-embebbing of translators.
