In the legacy DOS partition tables the space available was limited to 32 bits, while the GPT table specification provides 128 bytes for each block entry. The extra space can be used to store information related to the intended OS usage of each partition, by adding the corresponding Partition Type UUID. This has a number of benefits, described here: https://uapi-group.org/specifications/specs/ discoverable_partitions_specification/ Besides the automation this feature affords, I find it useful to know what a partition contains without having to mount it. On GPT labelled disks I make use both of the Partition Type UUID and the Partition Name. A quick glance at the gdisk output and if need be its 'i' option has saved my day from formatting the wrong partition more than once! ;-) --nextPart8369496.T7Z3S40VBb Content-Type: application/pgp-signature; name="signature.asc" Content-Description: This is a digitally signed message part.
