GPT GUID is one of the best FILESYSTEM-INDEPENDENT way of uniquely identifying a partition.
I am not sure if Linux supports gpt-uuids (I didn't find any hints of it via google!), but this sounds like it could be great news for Linux encrypted swap -- the current enc-swap recommendations destroy the partition contents on every boot, with a new random encryption-key and new `mkswap` inside it, so you have to refer to it like /dev/sda5. And then "/dev/sda5" partition gets destroyed on every boot, so the failure mode for wrong-partition is even worse than normal. But with a UUID stored outside the partition, it would be more possible to uniquely identify that partition. (Or a different encrypted-swap format, but no one seems interested in doing that :-( )
Maybe even the GPT Disk GUID can be used to reference a GPT disk (instead of confusion over whether it is (hd1) or (hd2) and so on.
oh, interesting, that could perhaps be nice for something -Isaac _______________________________________________ Grub-devel mailing list Grub-devel@gnu.org http://lists.gnu.org/mailman/listinfo/grub-devel
