Description Caspar Zhang 2011-02-09 16:00:29 UTC 
Description of problem:

When running `v7 plan', v7 would check required RPMs, if required RPMs are missing, it would try to install them, but it always gives the following error output even after installation succeeded:

Error: Could not install rpm 
"yum install -y xxxx" has output on stderr

This is because in V7_SRC/v7/command.py, 

 68         if self.errors and len(self.errors) > 0:
 69             raise V7CommandException(self, "has output on stderr")

And `yum install' will gives warning message via stderr:

This system is not registered with RHN.
RHN support will be disabled.
Warning: RPMDB altered outside of yum.

That causes error.

I doubt whether Line 68-69 are necessary for checking error, do we have any commands could be judged fail/success running only via stderr output?

Is there something to fix here, I'm not clear from the above if there is any side effect other than yum reports and error and subsequently v7 reports an error; fix the yum issues and the v7 problem reporting would be resolved?
