Running systemd inside a Container

Some context here - https://developers.redhat.com/blog/2019/04/24/how-to-run-systemd-in-a-container

With Docker you need to mount the host volume -v /sys/fs/cgroup:/sys/fs/cgroup:ro However this is not needed for podman

If Kubernetes cluster is still using Docker, this will not work in pod wihtout these mounts; but if using Containerd directly (kubelet--> Containerd-->runc) I am not sure

Folks, Leave me a comment / URL if something you like is missing!

Linux Desktop on Apple Silicon in Practice

I bought M1 MacBook Air. It is the fastest computer I have, and I have been a GNOME/GNU/Linux user for long time. It is obvious conclusion that I need practical Linux desktop environment on Apple Silicon.

Fortunately, Linux already works on Apple Silicon/M1. But how practical is it?

Two native ports exist.
