This is fine for now, I meant, what about all the networking ideas/projects around FreedomBox:


My real question is: does the DHCP-client fit into that model ?

What if you have a very integrated FreedomBox where you only run 1 webserver and multiple
application containers for different applications (maybe even static files mapped directly
on the webserver to a directory from the webserver). In that case you want it to be some what
static and not directly connected to the LAN or WAN.

Not that this is a real problem for Program Space, it can handle that just fine. :-)

I'm just wondering if people have a plan.

PS Seems the Docker folks are adding an in-container process too now:
