>Description:
NanoBSD has a utility shell script called save_cfg which helps keep /cfg updated with the modified configuration files in /etc. I have written an improved version with the following features:
* Recurses directories.
* Only requires file arguments the first time the file/directory is added to /cfg.
* Handles file deletions.
* Is named "cfgsync" so is much easier to type.
>How-To-Repeat:
>Fix:
--- cfgsync begins here ---
