It's still there. And though it is outdated I bet it was once right.

UNIFIX, as the message shows. UNIFIX is (or was?) a German Linux distributor, located in Braunschwieg (100km from my home, so I could take a look if no one believes in this ;)).

In 1995 or 1996 they sold a UNIFIX 2.0 distribution which was heavily modified not only to pass the posix.1 and posix.2 (IIRC) conformance test, but also too look more sysvish (I remeber yhey modified e.g. ps to take ps -elf for long output instead of ps aux).
