I have two identical GPT drives whose partitions have identical GPT
PART/UUIDs. I doubt they would auto mount correctly.

partx --show /dev/sdb

NR  START        END    SECTORS   SIZE NAME                 UUID
 1     40     409639     409600   200M EFI System Partition b88cc0a6-0aea-46c4-836d-4059e154dda0
 2 409640 1953262983 1952853344 931.2G G-DRIVE Mini         f4f104b8-b981-45e4-b0c5-f0f828d8acb8

partx --show /dev/sdc

NR  START        END    SECTORS   SIZE NAME                 UUID
 1     40     409639     409600   200M EFI System Partition b88cc0a6-0aea-46c4-836d-4059e154dda0
 2 409640 1953262983 1952853344 931.2G G-DRIVE Mini         f4f104b8-b981-45e4-b0c5-f0f828d8acb8

Note that these so-called UUIDs are different than the UUIDs
reported by blkid. The authors are creating confusion
here, and deserve a bug report.
