I don't think 'extras' has anything to do with it. It appears to be
done in rules/rules.d/60-persistent-storage.rules
When I do dumpe2ds /dev/sda1, I get:
Filesystem volume name: <none>
I suspect you have to add -L volume-label to mke2fs (or other partition
formatting tool) for at least one partition for by-label to be created.
tune2fs can also be used to add a label to a partition, but I don't know
if the udev would pick that up right away or if a reboot would be needed.
