[rrd-developers] [patch] rrdcached init script and spec file

Hi Daniel:

The init script does not work on my system (CentOS 4.x) as is, because
the `daemon` function which I have does not support --pidfile -- is
that argument necessary?

Also, as discussed previously, I think it would be a good idea to
create a 'rrdcached' user and group and start the daemon as that user
instead of nobody.  For application-specific (eg. Ganglia)
implementations, we can just put the necessary users (such as nobody,
apache, ganglia) in the rrdcached group.
