They're both based on 4.4BSD, but they have both diverged somewhat. The ELF support is one example. > I had access to a BSDI 2.1 server for a few months and man was it > fast!

Now I have 3.0, and I haven't got round to installing it. There's not much difference. At one point, I said "sure, BSD/OS is better than FreeBSD, but then you have to pay for it". Nowadays I can't point to anything that's decidedly better, but that could be lack of knowledge. > It was during this time that I discovered the other *BSD os's and decided > to convert one of my machines to FreeBSD, and I very glad I did.
