The rEFInd docs state:

Under Linux, you can learn a filesystem's label by using blkid, as in blkid /dev/sda1. The filesystem's label, if set, is identified by the keyword LABEL in the output. Some versions also return the partition's label and partition GUID (referred to as PARTUUID by blkid)

Yes, but drives with MBR also have a PARTUUID. It is in the format <disk identifier>-<partition number> where partition-number is a two-digit hex value.

I ship EasyOS as a image for a USB-stick, with MBR, and I would very much like to not be restricted to the "volume" parameter in refind.conf to be a f.s. label.
