I’m likely going to fork this and allow for base image selection as well. The images that are being minted by repo2docker for our use case are enormous with no common layers. Having the ability to use our “stock” (docker-stack + special sauce) base images will greatly decrease pull/startup time as each user gets a dedicated node that comes with our base images.

I think part of the issue is that repo2docker allows you to install operating system packages using apt, and since it’s at the OS level that means it’s often only configurable by root. As an aside, there’s another future problem here- if the base image is upgraded from https://github.com/jupyterhub/repo2docker/blob/cb4621f2544efba496f6cf58f6684846d7c49643/repo2docker/buildpacks/base.py#L18 to the next LTS then since packages may have been dropped or undergone breaking changes this could result in binder repositories failing to build or run.

Compare this with most (maybe all?) of the other buildpacks which can be run as a non-admin.
