LVM2 has inherited this from LVM which calls them UUIDs. It would cause too much confusion to change this terminology. But I'm willing to accept an LVM2 patch to uuid.c etc. which switches to generating compliant ones *provided that* it leaves the tools fully backwards- and forwards-compatible and does not introduce additional external dependencies by default. But I have no time to spend on this myself in the forseeable future, so before it gets applied, a patch will need to be self-evidently correct (by reading it incl. comments) and have evidence of thorough testing incl. PV created by LVM1, UUID displayed correctly in old-format using the patched code; PV created with the patched code in lvm1 format, displayed correctly by LVM1 tools; PV created with patched code in lvm2 format displayed and processed sensibly by unpatched lvm2 tools etc. Also affects tools that take --uuid argument [both formats to be acceptable]; and vgexport/import, vgcfgbackup/restore, vgconvert, and even lvchange -a will need careful testing (it relies on VG and LV UUIDs), though retaining the existing length internally and introducing mapping to and from this might be a good way to limit the amount of testing necessary.
