Description of problem:
==================================
The value for the broker of /etc/sysconfig/matahari is being ignored

***broker is up and working***

This was tested against v0.4.2-2....
Comment 3 Russell Bryant 2011-09-14 11:05:55 UTC 
Once I thought about this again, this is expected behavior.  /etc/sysconfig/matahari is only used when matahari is started as a service, not when you run the agent executable directly.  Can you please try starting it via the init script and verify that it works?
Comment 4 Dave Johnson 2011-09-14 15:31:56 UTC 
Yeah, this is not an issue.  Not sure what I was thinking.
Comment 5 Zane Bitter 2011-09-15 11:33:26 UTC 
I updated the man page to not imply that matahari-brokerd reads /etc/sysconfig/matahari-broker itself:
