  27     <para>The root filesystem used by the kernel is specified in the boot configuration
  28 file, as always. The traditional <emphasis remap="B">root=/dev/hda1</emphasis> style device
  29 specification is allowed. If a label is used, as in <emphasis remap="B">root=LABEL=rootPart</emphasis>
  30 the initramfs will search all available devices for an ext2 or ext3 filesystem
  31 with the appropriate label, and mount that device as the root filesystem.
  32 <emphasis remap="B">root=UUID=uuidnumber</emphasis> will mount the partition with that UUID as the
  33 root filesystem.</para>
