Describe the bug

Unable to run bootstrap role on vanilla alpine (virtual ISO) install due to missing python intepreter.

I am trying to run the bootstrap role on a brand new VM with alpine installed. Using alpine virtual ISO to install with default params.

Given that alpine installs extremely lightweight, there is no default python interpreter in the installation process, yet I was expecting that this bootstrap role would have detected it and installed python.

Running with gather_facts: true fails with the same error message but in the [Gathering Facts] task earlier.

Disabling the bootstrap_wait_for_host, will get the process moving a bit further; however it fails in that it cannot install sudo in the main repository. And the community repository is disabled by default in the alpine installation
