@Tristan107, you will see something like this
Cannot determine cgroup we are running in: No medium found
Failed to allocate manager object: No medium found
[!!!!!!] Failed to allocate manager object, freezing.
Freezing execution.
if /sys/fs/crgoup is mounted, it’s related to these issues https://github.com/systemd/systemd/issues/6477, https://github.com/systemd/systemd/issues/6477. So for now, we won’t mount it in the base images and you can just ignore the “failed to install release agent” warning.
