Very helpful for a specific binderhub instance to customize how images are built. Off the top of my head, two useful things would be to pass
--repo-dir
(so you can have this work with a persistent home directory but still get access to the files in the image), and--base-image
(so an install can use a different base image than rep2docker default).As it's a simple passthrough, I've added a unit test only (no integration test).
Fixes #1765
