Index of Difference Between PARTUUID and UUID


PARTUUID and UUID are not the same. They look different and they are different! Thats the difference:

  • UUID: specifies the file systems UUID
  • PARTUUID: The PARTUUID partition identifier is supported for the GUID Partition Table (GPT) and others


There are various options to find the PARTUUID. I find the best option is to leverage on the lsblk command, as with the right options it shows very nicely all PARTUUID‘s of your file system. The lsblk and blkid commands mybe are useful too and achieve the same.
