Install new logo/favicon from the command line

Is there any way to install different logos and favicon from the command line? I want to include them in the docker image produced by the launcher. Regular settings can be overridden by setting environment variables, but I don’t know how that would work for images.

I think that you could do it with some rails commands. You’d look at the upload model or perhaps an import script to see how to do that.

Or you could do it with a plugin that used the seed interface that’s used to add the default icons.
