I'm almost positive they were in place for the 4.3BSD release in 1986 which our university cs department upgraded to in early 1987. ufs's 8k block size is very deeply rooted in history. I know that SunOS 4.0 had it and I'm almost certain that it had 3.5 had it as default as well (but I only did a couple 3.2 and 3.5 installs before upgrading to 4.0.1). SunOS 3.x and 4.x came from BSD 4.2 plus a bunch of hacking. So we're pushing closer to 20 years ago rather than 10 years ago. BSD 4.0 was released in October 1980, per bsd-family-tree. I think that these defaults were there as well, but again, I've not looked at the cd to make sure.
