Should we make it a packaging policy that packages must own all 
directories and files that it installs in order to avoid umask 077 
problems like this where the installed software is effectively broken?

Also the latter bug is %post creates files with umask 077, leading to 
similar breakage.  Should then the rule be "use umask within %post if it 
creates files?"

Can rpmdiff check for this in the future?
