----

You can now start a systemd-nspawn container with:

 sudo systemd-nspawn --bind=${BOULDERCACHE}/ -D ${SOSROOT}/ -b
  OR
 sudo ./boot-systemd-nspawn-container.sh (rewritten on each ./create-sosroot.sh run)

Do a 'systemctl poweroff' inside the container to shut it down.

The container can also be shut down with:

 sudo machinectl stop sosroot

in a shell outside the container.

If you want to be able to use your sosroot/ with virt-manager,
you can set the DESTDIR variable when calling ${0} like so:

    DESTDIR="/var/lib/machines/sosroot" create-sosroot.sh

}

# Make it more convenient to boot into the created sosroot/ later on
createBootScript () {
    cat <<EOF > boot-systemd-nspawn-container.sh
#!/usr/bin/env bash
#
exec sudo systemd-nspawn --bind=${BOULDERCACHE}/ -D ${SOSROOT}/ -b
EOF
}
