You should be using something like:

  (file-system
    (title 'label)
    (device "ata-WDC_WD20EURS-63SPKY0_WD-WMC300539593-part3")
    (mount-point "/")
    (type "ext4"))

It literally means: Mount the block device whose label (in the ext[234]
sense) is =E2=80=9Cata-WDC_WD20EURS-63SPKY0_WD-WMC300539593-part3=E2=80=9D.

The root file system is mounted from the initrd, when udev is not
running; thus /dev/disk/by-id is not available yet, and it=E2=80=99s import=
ant
to use this 'label mechanism instead.

Thanks,
Ludo=E2=80=99.
