Do find the updated ARC case attached. The summary of the changes is as follows:
- updated the file layout as per Darren's suggestion. - included collectdmon as suggested. - added include files in the file layout which I had missed out. I am not sure as yet if we need to deliver only one collectd package i.e SUNWcollectd?. As I mentioned earlier, I have followed the lead of apache, lighttpd. mysql etc. all of which deliver a separate root and usr package.
