[Feature Request]: Need auto start container when use `--restart=always`

[BlackHole1]

When a container is started with restart=always, it will not automatically start if the system or WSL is rebooted.

That's interesting, podman appears to use systemd to implement the restart policy like this:

[Unit]
Description=A templated sleepy container

[Container]
Image=quay.io/fedora/fedora
Exec=sleep %i

[Service]
# Restart service when sleep finishes
Restart=always

[Install]
WantedBy=multi-user.target
DefaultInstance=100

Maybe we need a minimal init to take over our service just like systemd !

BTW, In theory we can take over the WSL2 init and make our init run as PID 1, but it's a bit of a hack, I'll try it.

See: https://github.com/containers/podman/blob/main/contrib/systemd/system/podman-restart.service.in

There are two ways to manage restart=always in podman. The first way is as you mentioned, by creating a systemd service for each container. The other way is the method I just mentioned, which uses a single systemd service to manage all containers with restart=always.

Yes

Please No! Hacking methods are always our last resort; their priority is always the lowest, and they will only be considered when there are no other ways to solve the problem.
Please investigate other solutions.
