Nope, I am firmly with Joe here on this one. The installer is the first major pain point new OpenBSD users are likely to encounter, and especially partitioning is weird, cryptic, and downright unhelpful. In real life OS testing and evaluation, I don't get to dedicate whole machines to any OS. No OS is that special, that important, or that versatile. I always dual-boot because that often uncovers weaknesses and assumptions in installers... just as the OpenBSD devels encourage people to fail hard, the OpenBSD installer itself fails hard in a multi-boot scenario. Example, to recreate if you are curious enough: 0. Set up a new PC (or VM, it doesn't matter.) 1. Install Windows (say, v10 as it's easy.) 2. Add a random Linux distro. For best results, have separate /, /home and swap partitions. 3. Now, try to add OpenBSD to that. For best results, do this by directing a friend who has never used Unix through the process, over the phone so you can't see the screen. ;-) If that's too easy, partition the disk with MBR so you have to deal with logical partitions too.
