And? Is that really important?

Yes, but how useful are they?
Unless these systemd-defined UUID are really relevant, I would prefer
that we use the shortcuts provided by genimage wherever possible, and
only rely on using the full UUID for special cases, such as the
board/sifive/hifive-unleashed/genimage_sdcard.cfg (PATCH 15/16).
This way, it would be pretty clear that we have the "common cases" (boot
partition, rootfs partition) and the "odd/special cases".
Best regards,
Thomas
