Podman will be used to test the generated Debian packages to ensure that
they work properly. However, this means that it is NOT shione and
therefore cannot solve letsencrypt challenge among many other things
that can only be done by shione. The goal is to have a staging area that
can mock the latter.
`certbox` argument parsing and plugin management isn't very suitable
when it comes to automating nginx configuration through Debian
packaging. It is not possible to instruct it to *only* generate
letsencrypt ssl configuration for nginx which breaks the postinst
script. Also missing fancyindex dependency was added.
