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.

Quality 100%


Installs rng-tools and starts the service.


Following platforms have been tested: * CentOS 6.6 * CentOS 7.1 * Fedora 20 * Debian 7.8 * Debian 8.1 * Ubuntu 10.04 * Ubuntu 12.04 * Ubuntu 14.04


  • node['rng_tools']['device'] - the device to use for random data. default /dev/urandom


The rng-tools.default template will use the device in the attribute. This is a non-default value because in a default installation of the rng-tools, the rng-tools service fails to start because the actual default device, /dev/hwrng (Ubuntu) or /dev/hwrandom (RHEL) doesn't always exist.
