CVSup question, which tag for 4.9-RELEASE?

[Bob Collins]

I am running a few boxes(n) on 4.9-RELEASE and am wondering about
updating the ports and source. Using CVSup, should I tag src with
RELENG_4, or RELENG_4_9? And what if any are the differences, that
are not already noted in the handbook? Up to this point, I have not
updated the system since install....

I think I have a rather good grasp of the topic, but there is a little
confusion on my part. I am thinking if I read correctly, using RELENG_4
will update to the latest in the 4.x branch and I'll be at 4.9-Current,
no? And RELENG_4_9 will be only updates to the 4.9 branch?

Thanks for the clarification.
