You may use a parallel command such as rshp or c3 to ask your nodes to
On MandrakeClustering/CLIC, urpmi parallel allow you to install packages
on a full cluster.
In your case, the following command executed on the server, ask each
node to choose the updates it needs from the sources the server knows
(the main distribution, updates from internet, your own packages etc..)
and then uses rshp&mput from KA-Tools (http://ka-tools.sourceforge.net/)
for copying/installing efficiently rpms on each nodes. It take the same
range of time for 1 or 200 nodes !
urpmi.update -a # <-- Read the lastest updates for your rpms sources
urpmi --parallel cluster --auto-select # <-- Ask each node of the
"cluster" group to update itself with the list of rpms that the server
