It should be split into two pieces: configuration file management (loading/saving/renaming/deleting) and calling into wg-quick via RootShell. The configuration file management part should then go back into the main package. This is in preparation for adding additional backends based on wg(8) and wireguard-go. Signed-off-by: Jason A.
