well. our lab is quite modest. we have about 15 or 20 machines. the
different machines all have our servers ssh key in their athorized keys'
key file. so i can ssh to all of the different computers without a
password. then i have an xml file on the server which describes the
different machines. using this xml file and a perl script running on the
server i do the updates. something like:

ssh root at machine  apt-get update; apt-get upgrade;

among other things, can be done. now what i'm doing isnt very fancy, but
you could probably fork off the processes 10 at a time or so. with ssh and
perl i can push pretty much whatever i want to the different computers. i
have a script that i run after installation which sets up the keys based on
files available via nfs. the post install script also initializes apt and
some other stuff.

 What difference does it make to the dead, the orphans, and the homeless,
 whether the mad destruction is brought under the name of totalitarianism or
 the holy name of liberty and democracy?
