Remember the Unicode quotes also in the pod documentation.

Most probably the lzma cflags are not needed.

Small typo.

If an empty output can be a valid output from file, then I'd say to
make this return None, and then act accordingly later on.

This can be simplified:

  | line :: _ -> line

Most probably this Some x match can be split in two cases:

  | Some "" -> ask_arch guess
  | Some x -> x

Could you please wrap this long line?

" ... the GPG key ..."
