--restart always has different effects in docker vs. nerdctl

[apostasie]

Description

When starting a container with --restart always, docker will not try to restart if explicitly stopped.

On the other hand, nerdctl will

Steps to reproduce the issue

sudo ./nerdctl run -d --name restarttest --restart always debian sleep 3600
sudo ./nerdctl stop restarttest
docker run -d --name restarttest --restart always debian sleep 3600
docker stop restarttest

Now, give it a few seconds then:

sudo ./nerdctl ps | grep restarttest
docker ps | grep restarttest

See docker documentation here:

https://docs.docker.com/config/containers/start-containers-automatically/

Specifically:

"always Always restart the container if it stops. If it's manually stopped, it's restarted only when Docker daemon restarts or the container itself is manually restarted."
