    berlin: Add a 'rootdelay=20' kernel argument.
    
    Previous attempts to boot the Btrfs RAID array failed with messages
    suggesting not all the drives were ready:
    
        [   64.434898] BTRFS warning (device sdb3): chunk 98847948800 missing
        4 devices, max tolerance is 1 for writable mount
    
    Hopefully a 20 s delay is enough to allow for the drives to fully
    warm-up before they get assembled into an array by 'btrfs device
    scan'.
    
    * hydra/berlin.scm (operating-system)[kernel-arguments]: Add
    'rootdelay=20'.
    [file-systems]</mnt/old-gnu>: Do not require for boot nor auto mount.
    </mnt/old-root-fs>: Likewise.
