We have UUID=, LABEL= for mount and fstab, I think PARTUUID=, PARTLABEL= matches this. We can always change that, if something better comes up before this gets official. :) Kay -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
