systemd based containers

[odra]

Hello,

Is there a way to run a toolbox container with an image that starts itself with "/sbin/init" (systemd container image)?

I tried to create one but it fails:

This is the image I am using: https://gitlab.com/CentOS/automotive/container-images/autosd.

What's the use-case/actual usage? You are trying to run fedora-toolbox as a system container or you want to run a system container in toolbox, or ? This may not be a good match for toolbox... Have you tried something like podman-desktop say?

More authoritative container people may be able to comment more

I want to run systemd inside the container, as the image I shared does.

That image is a developer environment one which is a perfect fit for toolbox, use case wise (IMO).

I have a couple of ideas on how to support it but I would like to know people thoughts on the idea itself, if it actually makes sense to support such kind of containers in toolbox.

I wonder if this is a duplicate of https://github.com/containers/toolbox/issues/176

In general, yes, I do want to make it possible to use systemd and systemctl(1) to manage units inside Toolbx containers for development purposes. I just didn't have time to figure it out, yet. So, ideas and patches welcome!

It is yeah, I will move comms. to that issue.
