Is there any reason skopeo and umoci is called as sub-process instead of used as a library?

[stgraber]

Mostly simplicity at this stage. Neither appear to be particularly designed to be consumed as Go modules and we also don't want to find ourselves importing too many indirect Go dependencies into the core of our project.

As both skopeo and umoci are readily packaged in most distributions, just using the external commands is best for now.

Would it be possible to get new commands/dependencies added to the release notes? Or maybe keep a running list in the packaging doc?

(This is amazing btw :)

one comment and one question, but lgtm otherwise.

Examples of normal usage:

stgraber@dakara:~$ incus launch docker:hello-world --ephemeral --console
Launching the instance
Instance name is: native-imp

Hello from Docker!
This message shows that your installation appears to be working correctly.

To generate this message, Docker took the following steps:
 1. The Docker client contacted the Docker daemon.
 2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
    (amd64)
 3. The Docker daemon created a new container from that image which runs the
    executable that produces the output you are currently reading.
 4. The Docker daemon streamed that output to the Docker client, which sent it
    to your terminal.

To try something more ambitious, you can run an Ubuntu container with:
 $ docker run -it ubuntu bash
