Comment 4 for bug 2012516

As mentioned in the docs, via the `--secrets` command line option you can provide a file with key/value pairs for secrets.

https://lpcraft.readthedocs.io/en/latest/cli-interface.html#lpcraft-run-optional-arguments

So, imho - at least for running lpcraft locally - this should work already, via providing the SSH key as a value (in the secrets file) and using the `run` command or even better the `run-before` command to put the SSH key in the correct location. That is certainly only valid for a local run, and not very streamlined.

I wonder whether SSH-keys are the only way to install from a private Launchpad git repository, or maybe there is an easier way via an token? @cjwatson

And yes, we do use lxc.
