Cfengine can run arbitrary commands at scheduled times, so it is capable as a replacment for cron. It also has package management built in for your package updates. It is in the same vein as chef & puppet, but "deployment framework" is not the way I would describe it. Deployment is only be a subset of what you can do with it. Cfengine3 was a major rewrite over version 2. The community edition is open source and should be available in Debian. The gentoo ebuild is a bit out of date currently. It also comes as a supported enterprise version which adds some sort of framework around the core - I've never personally looked into the enterprise features though. Bruce -- :B
