This is a good idea and was what I was planning to do.  For Ganglia,
we would just put both apache and ganglia users in the rrdcached
group.

I guess I could potentially add the rrdcached user/group creation in
the RPM spec file.

BTW it sounds like you have already some ideas about the rrdcached
init script -- do you want to go ahead and code that?  I could then
put it into the spec file as well.

I wonder if we should ship rrdcached in the standard rrdtool
distribution RPM, or should we have a subpackage called
rrdtool-rrdcached which will include all the extra stuff which comes
with rrdcached.

Thoughts?

Thanks,

Bernard
