cdc8d9c4
HH		 30specification is allowed. If a label is used, as in <emphasis remap="B">root=LABEL=rootPart</emphasis>
31the initramfs will search all available devices for an ext2 or ext3 filesystem
32with the appropriate label, and mount that device as the root filesystem.
3b403b32 33<emphasis remap="B">root=UUID=uuidnumber</emphasis> will mount the partition with that UUID as the
