The prompt comes from pacman, and answering no there causes pacman to exit with a non-zero status (indicating failure). We don't have a way to know if pacman failed because the user cancelled installation or because of another error. In any case, at best we can show a better error message.

Note that for any prompts that come from aconfmgr itself, pressing n results in a different message.

#16, if implemented, will allow skipping some steps, but you will need to run aconfmgr with --paranoid to make it prompt before invoking pacman (it doesn't do so otherwise because pacman has its own prompt).
