#!/bin/bash -e
if [ ! -d /tmp/sys2 ]; then
# `ip -netns t exec ...` will try to mount sysfs. But kernel rejects that in
# the container, unless a writable sysfs is already mounted. Due to --priviledged,
# we have /sys mounted rw, however, ip will first unmount /sys before trying to
# remount it. We thus need it mounted as rw one additional time.
#
# Let's do this setup step once, and never clean it up.
