What > configuration info can you keep in puppet? Puppet can manage individual files, packages, services, users, groups, and a lot more. The beauty of it is that you use a simple language to define what your system(s) should look like and puppet then ensures that they match it. For example, you could have puppet manage your sudoers file. You would edit the file in one place, on the puppetmaster (aka your puppet server). When you make a change to that file, any of your puppet managed systems will have the updated sudoers file installed the next time they check in with the puppetmaster (by default this is every 30 minutes). Even better, you can tell puppet that whenever a file is modified that a service must be reloaded or restarted. So if you change httpd.conf, puppet will deploy it to your systems and then reload httpd. To get a better overview, you might want to spend a few minutes poking around the Puppet wiki at http://reductivelabs.com/trac/puppet/wiki/ . You can combine puppet with a provisioning tool like cobbler¹ and have a base system up and fully configured in just a few minutes. Once you have defined your systems configuration, you can worry less about individual boxes because it's so easy to blow one away and re-create it from scratch. Your puppet configuration can be kept in a version control system like git which you can easily use to keep backups of the configuration files you care about (which are generally only a small fraction of the files on a given system). ¹ https://fedorahosted.org/cobbler/ -- Todd OpenPGP -> KeyID: 0xBEAF0CE3 | URL: www.pobox.com/~tmz/pgp ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Years ago fairy tales all began with "Once upon a time...", now we know they all begin with, "If I am elected..." -- Carolyn Warner
