- Rename `device_freebsd.go` to `device_bsd.go` and `hardware_freebsd.go` to `hardware_bsd.go` to reflect broader BSD support (FreeBSD, NetBSD, OpenBSD, Dragonfly). - Update build tags in `device_bsd.go` and `hardware_bsd.go` to include FreeBSD, NetBSD, OpenBSD, and Dragonfly. - Rename `device_linux.go` to `device_unix.go` and `hardware_linux.go` to `hardware_unix.go` to generalize Unix support excluding Darwin-based systems and BSDs. - Add specific build tags to `device_darwin.go`, `device_unix.go`, `hardware_darwin.go`, and `hardware_unix.go` to correctly target their respective operating systems. - Ensure Windows-specific files (`device_windows.go` and `hardware_windows.go`) are correctly tagged for building on Windows.
