Curtin’s assumption is that a fairly rich Linux (Ubuntu) environment is booted.

But if your image is not Linux (Ubuntu) based, you could customize the image via:

1. Understand curtin stages
   http://curtin.readthedocs.io/en/latest/topics/config.html
   Stages:

curtin install with launch

Curtin has a test suite named vmtest. It has loads of configs for installation that put curtin through a battery. As of this writing it runs 192 installations on amd64 covering all supported ubuntu releases. It runs nightly under jenkins. See example results in the curtin-vmtest-devel-amd64 job.

If you're interested just a general use of curtin without starting a VM, see another article 'Curtin Development on uvt-kvm'.
