It requires that you add a user named "chuser".

You are welcome! Once it was new to me too and somebody else gave me the

I don't know, but regarding /etc/resolv.conf for systemd-nspawn there

At least my Ubuntu 15.10 and my Arch Linux, both based on systemd,
shutdown the a container started by"systemd-nspawn -bqD /mnt/moonstudio"
and not the "host".
