Perhaps we're not talking about the same concepts. Obviously we aren't
going to use msdos partitions. The question is, are we using msdos-
style partition tables? If so, then the fact is, there's nowhere to store
uuids for all partitions. That has nothing to do with whether or not
other O/Ses will try to read the partition.
It comes back to the same point --- you can't have uuids for normal
block devices. You have to have some sort of superblock in the
device. There is just nowhere outside the device (where by "device"
we mean partition, so "outside the device" means "in the partition
tables") to store the uuid if you are using msdos partition tables.
