He's who has read all the documentation and has prepared all our rules. I've read docs, and understand the rules and the way it works, but he's the best person to advice on the best tutorials and beginnings. All what I've read is at http://reductivelabs.com/trac/puppet/wiki/PuppetIntroduction & http://reductivelabs.com/trac/puppet/wiki/DocumentationStart So as Antonio reads this list, I encourage him to send an email with his thoughts on it. In brief, you can think of puppet the same as of cfengine, but: - rules are much easier to write and understand - the development community is much richer than cfengine, it's very agile and suggestions are implemented pretty fast. There is also an alioth project maintaining puppet in Debian, so it's in a good state for us. On the opposite, we've found problems when mixing different versions of puppet between the server and the clients. That's logical, but it's a pain until you can fix it. Today we're in a intermediate stage and have etch, sarge and lenny servers, and that's something hard to maintain even with puppet. Some time ago, Petter Reinholdtsen suggested me to put our puppet rules on a subversion machine. There are very particular rules that only make sense for us, but Antonio has also developed very nice rules to upgrade and install safely packages on the ltsp chroots very easily from a central point. There are also some other rules that might be useful for more people with similar implementations. So, maybe it's already time to try to find some time slot to setup that svn... Regards. José L.
