@PCOWandre @resuna It was indeed SunOS up to 4 that was BSD-based, AFAIK from the start. (4.0.3 when I finally got access to the coveted Suns at the university, work as well as study. At my student job I got the task to install "all that GNU software" on the first SPARCstation 1 they bought — a night and a day of pure fun. No "./configure && make install", rather real configuration work at the time. The best thing: Emacs with native SunView support.)
