Subject: [Rd] Option to set permissions on directories and files after
 package installation
In-Reply-To: <20658.37976.821700.411018@max.nulle.part>
Message-ID: <0CAEE2B1235DF643B0F5E1EAE1487B5309545D7B@023-CH1MPN1-042.023d.mgd.msft.net>

I second the request to allow specification of the permissions to use when
installing packages, preferably controllable via a site-wide configuration
