Install of all packages

Dear All,
me again. Sorry - you must be sick of my questions!

Here is a snippet of my current.conf

[CERNCC]
label = CERN-CC
name = CERN Computer Centre addons
parent_channel = 
arch = i386
os_release = 7.2
description = RPMs which FIO group make to add to interactive and batch
machines

rpm_dirs = /afs/cern.ch/project/linux/redhat/pro/addon/cc/RPMS/i386
           /afs/cern.ch/project/linux/redhat/pro/addon/cc/RPMS/noarch

xrpm_dirs = 
src_dirs = 
db_dir = /var/current/redhat-7.2/CERN-CC/current



My aim is that when we create new, extra packages for our machines that
these will be automatically installed when up2date is run on the
clients.
I think I got some fundamentals of the up2date mechanism mixed up.

Say I create a package called CERN-CC-package
I then put it in the appropriate (...addon) directory then re-create the
channel.  So far, so good.
However, up2date -u does not automatically install a package which is
not already on the system.
I've tried wildcards like   up2date --nox -u *  which doesn't work.

Any ideas maybe for a work-around?

I'm no Python hacker - but I will try to look in the sources of up2date.
