Subject: Add podman static build
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

We’re now able to build a static podman binary based on a custom nix
derivation. This is integrated in cirrus as well, whereas a later target
would be to provide a self-contained static binary bundle which can be
installed on any Linux x64-bit system.

Fixes: https://github.com/containers/libpod/issues/1399
