So are you (and Alex) saying that the CF parameter to rrdtool graph will
pick an RRA with the corresponding consolidation function?  Ie,

Find the RRA with the best resolution *AND* matching CF, and then
performing further consolidation using the CF if necessary

I didn't think that was clear from the docs, though of course it's the
sensible behavior.

I just satisfied myself that it does work this way by trying to graph a CF
for which no RRA exists.  rrdtool complains "the RRD does not contain an RRA
matching the chosen CF".

Great, thanks!
Bryan
