title: How can I detect OS version in Go
body: <p>Relatively new to Go. Seems trivial, but I can't figure out how to detect the OS version. I know I can use <code>runtime.GOOS</code> and <code>runtime.GOARCH</code> to get the platform and architecture, but say I know I'm on linux but I want to find if I'm on RH6 vice RH7, etc. is what I'm trying to figure out.</p>
