I just noticed that the file I ended up editing was 99-systemd.rules,
which is part of systemd. This was the file that made most sense when
I was looking trough all the .rules files I had on my system.

UBI is a common file system that is used on raw FLASH systems, in the
embedded world.

Would you consider adding that line in upstream? IMO it fits along
side SUBSYSTEM=="block", TAG+="systemd" that is all ready in the file.
But I might me "embedded" damaged for requesting this...
