Since we are moving to docker-compose how do we uininstall OMV-Extras?
The compose plugin does not replace omv-extras. omv-extras has always been a plugin that adds the omv-extras repos to OMV. It just used to have docker functionality that did not make sense. I have moved that functionality to the compose plugin. If you remove omv-extras, you will remove the compose plugin and omv-extras and docker repos.
