[zowoq]

@ofborg build podman.tests

@ofborg test podman podman-dnsname podman-tls-ghostunnel

[roberth]

This import is unnecessary because it is not a dependency.
There's a dependency relation between the two modules, but it's the other way around: network-socket-ghostunnel.nix can not exist without podman-network-socket.nix, so it's actually inverted.

Not sure I understand if you're suggesting a change or not?

Do you want it moved here with the other imports?
