Description of the feature request
I would like to be able to select an OSX / Ubuntu machine with as few things as possible pre-installed.
Use case / for what or how I would use it
I would like to test an ansible provisioning with bitrise. This provisioning installs different things like node via nvm. My current workaround is uninstalling everything bitrise installs, but that is not the nicest solution.
As far as I understand your setup this would be “just” leaving some steps out in the setup of the VMs.
