Description

Hello. This is a request for ACI support in the systemd-import tool. This tool[1] was introduced[2] in systemd 2.19:

A new tiny daemon "systemd-importd" has been added that can download container images in tar, raw, qcow2 or dkr formats, and make them available locally in /var/lib/machines, so that they can run as nspawn containers.

Support for fetching and extracting App Container Images with this new tool would be much appreciated.

Contributor guide

Research direction
Study the systemd import codebase to understand how image formats (tar, raw, qcow2, docker) are handled, then extend it to support App Container Image (ACI) format by implementing parsing and fetching according to the appc spec.
