panic after installation

[xoac]

I just installed mn and do

mn list 
thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: Os { code: 2, kind: NotFound, message: "No such file or directory" }', src/libcore/result.rs:1009:5
note: Run with `RUST_BACKTRACE=1` for a backtrace.

and back-trace:

thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: Os { code: 2, kind: NotFound, message: "No such file or directory" }', src/libcore/result.rs:1009:5

I think it's due to some configuration file that is missing?

Thanks very much for raising this. I'll take a look!

This should be fixed by #19. Do you mind letting me know if that resolves the issue?

(The bug was that mn was creating the file but not the directory, and the tests only tested for the absence of the file, not the absence of the directory.)

mn list                                                                                                                                                       
You don't have any mnemonics yet.  Use `mn add <MNEMONIC>` to create your first mnemonic.

Thanks very much for the prompt follow-up and the thorough bug report—if everyone acted like that, open-source software would be in vastly better shape.

Very much appreciated!
