The tag is there correctly (i.e. as you ca see in the TAGS= field, which
includes systemd for both cases).

My edcuated guess is that this is a result of you having a partition
table on top of md, which causes the md rules in 99-systemd.rules not
have ay effect on the partition block devices.

Kay, Harald, could you please have a look into this? The current udev
rule probably needs some updating to deal with setups like these.
