Another confusing link tag, why is it here?

Didn't Krzysztof already comment about the node name here?
Additionally, the "camsv1" label doest appear to be used, so should be
dropped.

You're right about the label, it should be dropped. Regarding the name,
as far as I understand, Krzysztof was fine with specific names when no
generic alternative can be easily found, which I think is the case here.
If my understanding is incorrect, could someone help finding a better
name ?
