Is there a better approch than running sleep +Inf as nest container run cmd?

[castedo]

Cnest is hard coded to run sleep +Inf as the background process that is started for a nest container. It's just there to be started upon the first cnest command (podman exec) and to be killed when the last cnest (podman exec) session ends.

Is there some preferred init process that should be used instead of bash running sleep +Inf?
