Actually not better but older ;) IIRC, /etc/os-release was only
introduced in 13. But then, it's probably "better" just as long as 12 is
still supported...

With lua scripts, you can't even use freebsd-version because execution
is very restricted for them in pkg. And for some features (like e.g.
dynamically creating a pkg-message output), you need lua...
