I feel like this is where I've landded: https://abstrusegoose.com/474

I've installed a clean TKL LXC on bare metal. The automatic network config didn't work, but I've worked around that. I can connect to lxc server via webmin and ssh and do stuff. Question is, now what? How are sub-containers installed?

https://www.turnkeylinux.org/lxc references 'Turnkey LX Template' which by description does what I'm after, "Download and create a container of any TurnKey appliance", but that script doesn't exist on my new system:
