Hi, everyone, could you please clarify a bit about how FEATURE_GROUPS [1] parameter is handled in Fuel. Currently we have it specified at ISO build stage, while from the description of it it looks like it is just a UI switch which doesn't change anything deep inside the code. Can it be changed at master node deployment stage, after master node deployment? Can we use exactly the same nailgun package to install all the different "flavors" just by changing configuration parameter after package installation?
