Types are by definition not unique. The symlinks in /dev/disk/by-*/ are *expected* to be unique. We handle duplicated labels, but they are specified by humans, multiple partitions with the same GPT types are just normal expected behavior; and they would have no order or priority, they just overwrite each other depending on probing order. We should not add such things, the logic to find these volumes at bootup are better handled by a specific program like systemd's systemd-gpt-auto-generator, without putting unreliable and unpredictable content into /dev. http://www.freedesktop.org/software/systemd/man/systemd-gpt-auto-generator.html http://www.freedesktop.org/wiki/Specifications/DiscoverablePartitionsSpec/ Thanks, Kay -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
