Therefore any process can start up with a PID of its choosing providing you create a namespace for it and don't fill it with other stuff first. The idea here is that you can suspend a whole container(/namespace) full of processes with virtual PIDs that may be talking to each other by PID, write them out to disc, and then at a later point recreate all the processes from the image into a new container with the same virtual PIDs (but new real PIDs) and they won't need to any of the wiser.
