 If you are starting from scratch without a `build/conf` directory you can just:
 ```
 $ cd openbmc
-$ TEMPLATECONF=meta-openbmc-machines/meta-openpower/meta-rackspace/meta-barreleye/conf . openbmc-env

 The first is the easy case, and largely involves picking the system

 The second case can be helped with Yocto's `devtool`. After running
