Author here - I step away for a few hours expecting HN to ignore yet another self submitted article and look what happens! tptacek's comments sum up the point - hence the qualifier of "pure". I think the SysAdmin role is rapidly evolving to look more like a programmer's job description from several years ago. Sure, someone still has to write the puppet configs and monitor and manage the deployment, but that person is a far cry from the skillset and job description of 5 years ago.
