Currently, nixos will allow for interface names with special characters such as the hyphen to be used. This presents a problem when using systemd device names as the namespace paths are separated using hyphens. Within systemd, if a device name has a hyphen it should be replaced with the escape sequence \x2d. This patch sanitizes all interface names before they are used in a systemd device string.
