> 1) what is the main difference between FreeBSD and OpenBSD? FreeBSD has more. More users, more developers, more features, more drivers, more ports, more money behind it, more settings to tweak, more bugs. By comparison, OpenBSD has a much bigger focus on cohesiveness, consistency, and sound defaults (e.g. custom kernel configs are discouraged/unsupported). I'd argue that OpenBSD has a more usable base system (including things like X11, doas, and tmux). > 2) What is the state of RaspberryPi support in OpenBSD? "Support" is nonexistent, but I think there have been a few changes in armv7 for Pi 2/3 and a couple developers are slowly working on it. Don't hold your breath. > 3) Is there some known big issues with video/wifi hardware in OpenBSD? The open-source Radeon drivers are pretty outdated at this point (I think the latest adapter with full acceleration support is something in the Radeon HD 7000 family), the Nouveau driver isn't ported, and there aren't proprietary drivers, so you don't really have the option of using a recent discrete GPU. Most effort goes into the Intel drivers (the developers use laptops a lot). 802.11n support is still pretty new and hasn't seen a huge amount of real-world validation yet. Drivers for n-capable hardware are older/better tested, but people have mostly run them in 802.11a/g modes. |
Not to mention an actually pleasant /bin/sh (a modified version of pdksh; compare to FreeBSD's extremely minimal version of ash which is (sometimes) useful for running scripts and not much else).
