Just linux blkid used something other. Basically Linux was incompatible with whole world and I think this was a bug. Also UDF specification say something that LVI is displayed to user. IIRC also Grub2 uses LVI as label identification. So I do not agree with reverting back old behaviour which is incompatible with everything except old util-linux versions... -- Pali Rohár pali.rohar@xxxxxxxxx -- To unsubscribe from this list: send the line "unsubscribe util-linux" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
