For my case, renaming the appropriate RRD files seems to be enough (e.g.
disk-3-0.rrd becomes disk-hda.rrd on my system). This is what you mean
when saying breaking backwards compatibility or are there other
implications I'm not aware of?

Oh, right, I hadn't thought of that. Maybe because I've long forgotten
much of the Perl I once knew. :-)

Since I've been running collectd for about two days, there isn't much
data to lose so I might try that.

I somehow managed to miss it when looking at collectd.h; thanks.
