Container doesn't have IPv4 with systemd version 256

Hello,

I have a container with archlinux.

I notice I do not have internet with this container after an update. After some investigation, I do not have IP address.

The issue appear after applying this package
systemd (256.2-1)
systemd-sysvcompat (256.2-1)
systemd-libs (256.2-1)

I need to downgrade to version 255.7.
I see there are breaking in systemd about IP forwarding but I am not able to fix my issue.

Any idea ?

I recreate the container and this is fine now
