I ran NetBSD 0.8 on my Amiga 500 (with a 68030 w/MMU, 68881, and SCSI hard drive sidecar), which co-existed in the same timeframe as Commodore's release.

Other than just than "we can" and historic interest, I can't imagine why anyone would choose to run System Vr4 over 4.4BSD, especially since the latest NetBSD 11 release still fully supports Amiga[0]

Nostalgia is my guess.

SVR4 on Amiga was the first SVR4 commercial release IIRC. Solaris 2.x came later, but not much later.

At Sun we had a saying for referring to garbage from the SVR4 that we had to fix, rewrite, or terminate with prejudice over time (think STREAMS, XTI, and all that, but also much of userland): 'it came from New Jersey'. So, yeah, I wouldn't want to run SVR4 for any reason other than nostalgia, and honestly not even nostalgia. For me nostalgia is for OpenSolaris and such.

I tried to get NetBSD on an Amiga way back as well and that was supposed to be my gateway from home computers to a real OS, but there was some problem with getting enough or working hard drive space or something that I can't recall exactly anymore.

So close, but still so far. It took several more years before I got some hardware that would run either NetBSD or Linux.

As an Amiga user, I don't even get the nostalgia for Amiga Unix. I don't have nostalgia for early versions of the various Unix versions I've used. It doesn't hit nearly the same as using AmigaOS on the Amiga did. Partly, I guess, because it's not different enough from what I use now.

Your 500 had a 030?
