-This script does not make the namespace be named like ip does, because
-the naming is not necessary, although it could have been done with some
-more work. For debugging and joining the namespace with a bash shell, I
-use nsenter -n -m -t \$(pgrep PROCESS_IN_NAMESPACE) bash. Note: if I
-knew how to easily ask systemd what pid a unit has, i would do that.
+If we aren't creating a named network namespace, to join the namespace
+with a shell, I use:
+nsenter -n -m -t \$(pgrep PROCESS_IN_NAMESPACE) bash

+If we do create the netns, to join it with a shell, we can do
+/usr/bin/nsenter --mount=/root/mount_namespaces/NAME --net=/var/run/netns/NAME bash
