Issues with OpsWorks

[darionalanya]

The dependent cookbook, selinux_policy, require Chef 12 to run which is not available via OpsWorks. We needed to clone selinux_policy v1.1.1 and then make two further modifications so that the cookbook worked properly:

• added if respond_to? for the source_url and issues_url lines
• Removed the dependency on yum
