I am just in the middle of setting up something quite similar to this.
We chose to rsync the configuration files, but NFS would work just as
well. Automatic upgrades are made with a cronjob running apt-get update
+ upgrade with noninteractive debconf frontend.
For package installations/removals I wrote a small script that converts a
command-line like 'install galeon evolution' to it's dpkg-selections
equivalent:
galeon install
evolution install
This list is then fed to dpkg --set-selections on each host, followed by
apt-get dselect-upgrade which does the actual installation or removal. I
know this is not perfect, but quite painless... until you really do need
to make host-specific configurations.
rsync and the package installer both use SSH with preinstalled,
restricting SSH key so that they are relatively safe.
If you have any comments about this approach, I would love to hear them.
