Edit /etc/sysconfig/rhn/up2date , change

storageDir[comment]=Where to store packages and other data when they are retrieved


keepAfterInstall[comment]=Keep packages on disk after installation

There is a risk associated in the sense that there is no synchronization
of the downloads, and I don't know what would happen if machine A and 
machine B try to download the same RPM at the same time, but the worse
which can happen is a corrupted package which will be detected by the
MD5 checksum check of rpm, will be reported and manual intervention can
then clean it up.
