Install script fails at line 62 in a LXC container

[mihanson]

I was trying to install readsb via your install script and the script throws a "Permission denied" error when trying to mount root as rw. The script is running under sudo and I am inside a LXC container.

mihanson@ads:~$ sudo bash -c "$(wget -O - https://github.com/wiedehopf/adsb-scripts/raw/master/readsb-install.sh)"
