# By convention a named network namespace is an object at /var/run/netns/NAME that can be opened. The file
# descriptor resulting from opening /var/run/netns/NAME refers to the specified network namespace. Holding that
# file descriptor open keeps the network namespace alive. The file descriptor can be used with the setns(2) sys‐
# tem call to change the network namespace associated with a task.
