Really? What duplication did you actually find? I count a few small ones in buildMounts and ReadPrompt, maybe 20 lines or so, but hardly anything worthy of such an epithet.
Admittedly, the parsing & escaping code and some utility functions could be moved outside to shrink the file, but otherwise I'm having trouble finding issues with the code.
