“Nothing special”, apart from that it is running in a container and not fully plumbed in to the actual OS.
As per your description it would seem the app still wants some sort of interaction with the WiFi management APIs (as opposed to pure network comunication), if only in the background, to get to that step.
Hardly “same” as it is a completely different application. I’m sure that if you got gphoto2 running on SFOS, it would work fine there too.
