Again, not sure if an eudev thing, or instead the lvm metadata not cached by the daemons, or something else.  I'm no expert on this.  I've always just used lsblk -f...  Whatever it is, I don't know if whatever is missing also affects other things besides lsblk -f...

Just in case, if I recall correctly, on the live base artix-s6 installation, lsblk -f was working fine.  So perhaps it's not about eudev at all, and still something about lvm metadata, :(  Just an additional data point...
