The default motd on OpenBSD is "Welcome to OpenBSD: The proactively secure Unix-like operating system."
You can argue what exactly is or isn't "Unix" until you're blue in the face as there are multiple definitions you can use (lineage of the code, trademark, posix compliance, etc.) It's a very boring discussion though.
- Maursault 4y agoOpenBSD was forked from NetBSD which is derived from 4.3BSD-Reno, and like all BSD, ultimately derives from Research UNIX. The original Berkley Software Distributions all referred to themselves as Unix and upon logging in a user would see a "Welcome to BSD Unix" text banner. Linux derives from Minix which, beyond using a BSD userland, is otherwise unsourced from and unrelated to BSD and UNIX. GNU is a recursive acronym that literally means "GNU's Not Unix!"
