The 3rd prerelease of Bcfg2 0.9.6 is now available.
For those not in the know, Bcfg2 is a system that:
helps system administrators produce a consistent, reproducible, and verifiable description of their environment, and offers visualization and reporting tools to aid in day-to-day administrative tasks.
Basically it comes down to managing your system configurations from a central location and then pulling (or optionally, pushing) the configuration data down to each machine. This ensures your machines are in a known state, and eliminates the need to go around to each one and manually verify or copy configuration.
Other tools in this category include Puppet or CFEngine, but IMO Bcfg2 trumps either of those.
Check it out. If you have any questions, feel free to come to #bcfg2 on irc.freenode.net and someone can surely help you out.
