| Fine, they are different operations :)

...more than the assymetry, I guess I am not sure what is the "recommended"
way to restart an application, while ensuring filesystem (and network)
are correctly restored by user.

	ns_exec --cpuim -- /usr/bin/restart --wait < checkpoint-image.1

assumes fs/network are setup. Hence the "login" to the container.
