Current problems:

➜  dura git:(master) rg 'unwrap|expect'
src/main.rs
11:    let dir = std::env::current_dir().unwrap();
14:            if let Some(oid) = snapshots::capture(&dir).unwrap() {
38:    config.set_watch(path.to_str().unwrap().to_string(), WatchConfig::new());

src/log.rs
68:        let path = Config::default_path().parent().unwrap().join(file_name);
78:                eprintln!("Unable to write file {}", path.to_str().unwrap_or("n/a"));

src/poller.rs
23:    let repo = path.to_str().unwrap_or("<invalid path>").to_string();
