It appears that Warner Losh <imp(a)bsdimp.com> said: Yes, it was a commercial peer of the other BSD forks. I used it for quite a while until the company was sold and refocused on embedded applications. It wasn't hard to move to FreeBSD which is what I am still using. When I moved tp upstate NY in 1996, I wanted an Internet connection for my work. So I called up the local independent telco who told me they had just rolled out their new Internet service. Great, can I have a T-1? Dunno, have to ask the boss. They called back and said there was no techncial problem but nobody in my small town had ever ordered a T-1 before so they had to get a T-1 rate added to the tariff they had on file with the state. That took about a month, after which a guy in suspenders with a ladder showed up, ran the two-pair wire, he and I looked at the manual for the CSU/DSU I'd gotten, wired it up, and whaddaya know it worked. (It was worth the wait, their price was half what Verizon would have charged in Ithaca.) Well, that part worked. They hadn't anticipated leased line customers who wanted a /24 (which they just let me use, this was 30 years ago) so they added me to their internal OSPF network. I was running BSDI on a cheap 386 box, set everything up, and oh crud, the routing daemon didn't work due to bugs. I contacted BSDI and, in one of those things that would be too strange to be fiction, we found that the guy at Cornell who'd written the open source routing daemon now worked for BSDI and lived about 10 minutes from me. I called him up, he sent me some patches, and everything worked. I could not have asked for better software support. He and I are still the local nerds which you can tell because his car's license plate says TCP-IP and mine says IPV4. R's, John

There was much drama and it didn't go anywhere. Sun was pretty much the only company to make money off of BSD and it was because SunOS was famously known as "a bug fixed, and completed, BSD". wnj had the mmap docs somewhere, he had the idea, Sun actually implemented it and realized that a page cache and a buffer cache are two caches of the same thing (read/write went through the buffer cache, mmap went through the page cache) and unified them. Killed the buffer cache except for directories and maybe inodes. Took the other Unix implementations at least a decade to catch up. Ask me about HP-UX. BSDi never did anything like what Sun did but they wanted the money, hence the drama.
