Simplest way to make simple custom templates, like LXD snapshots

[Alex1]

With LXD one can take a snapshot and then easily use that snapshot to create a new template. You can do the same with proxmox, backup and then restore to create a new container, but then you have to change network settings and so on afterwards.

Is there a super simple way to just add a current container as a template so that we can add like a user and a SSH-key to the template(or maybe just chef, salt or something for further configuration) and then use it for other containers using the create CT flow? Or do I have to use DAB?

I'm thinking of something like this, but for LXC:

We plan to implement the same template feature as we have for VMs. Such templates can be thin-provisioned, and you can edit the config as you like.
