I agree it would be nice. I have a question for Henrik prior to
implement it. The RRAS are added individually in each /rrd/*.c backend,
and they get calculated for every status message coming in, (file
creation parameters calculated even if the file already exists. That
part can be moved inside create_and_update_rrd(), making  Hobbit faster.
I'll do it that way only if you don't have future plans underneath that
duplication of code. If you do, I'll add the trackmax test in every
individual rrd backend.



(and I'd love to see that feature in the mainstream hobbit, too :)
