[syslinux] extlinux support for root= ext2 label and/or uuid

[Andrew Paprocki]

Is it possible to specify the root device in extlinux.conf by an ext2
label or uuid? How difficult is it to add this support if it is not
there? I am in a situation where this is needed and my fstab is
configured appropriately, but extlinux.conf still needs to be manually
updated when the root drive changes to a different scsi device (due to
the number of drives on the bus and the order of the controllers).

Thanks,
