FreeBSD and OpenBSD’s inetd are based on a same codebase. However, they have different features and OpenBSD have some features that FreeBSD is lacking at present. For example, per-interface binding, etc.

I plan to merge OpenBSD’s rev. 1.28 to FreeBSD. It seems that the code structure is different between the two. I have merged about 5 hunks out of 12 hunks. Tests pending.
