[csw-maintainers] Ganglia using rrdcached by default?

[Daniel Pocock]

rrdcached makes the Ganglia graphs appear much more quickly, and reduces
IO load on the reporting server. It is present in the rrdtool packages,
but no init script is supplied.

Various issues come to mind:

a) should the ganglia packages use rrdcached by default?

b) how to start rrdcached?  Should rrdtool supply an init script?  Or
should it be done from the gangliagmetad init script?

c) Can initsmf declare the dependency (gmetad depends on rrdcached if
configured in this way)?

Or would this over-complicate the relationship between the gangliagmetad
and rrdtool packages?
