Should add, a problem with `rsync-auto` is some files in node_modules (bcrypt, among others) are compiled at runtime, and produce different outputs for Mac/Linux - you can't just copy them from Mac to Linux and expect it to work. Probably some things we could do to hack around this but it didn't seem worth it.
