Supermarket Belongs to the Community

Supermarket belongs to the community. While Chef has the responsibility to keep it running and be stewards of its functionality, what it does and how it works is driven by the community. The chef/supermarket repository will continue to be where development of the Supermarket application takes place. Come be part of shaping the direction of Supermarket by opening issues and pull requests or by joining us on the Chef Mailing List.

entropy cookbook

This cookbook will install an entropy gathering daemon on lots of different platforms.

Applications can hang or become very slow due to lack of entropy, especially when generating
keys (like RSA or GPG keys). Installing an entropy gathering daemon gives the OS a relatively
high quality source of entropy.

Entropy daemons


Right now, this cookbook only supports install haveged. This is an entropy gathering daemon that
I have a lot of experience with and that is well supported on lots of platforms. I am totally open
to implementing recipes for other entropy gathering daemons as well.

Supported Platforms
