alt Hacker NewsHave you tried such Openbsd installations vs FreeBSD? I forget the differences between OpenBSD and FreeBSD, so forgive the naivety. (I think NetBSD is more for embedded stuff, and Ghost and Dragonfly are more for conventional desktop use-cases if i recall correctly.)
I'm asking because i have not touched any BSD for over 2 decades...and I'm getting the itch to try some out...and was wondering if for server-type use cases (like you noted) whether OpenBSD is preferred over FreeBSD or the reverse, and why? Thanks in advance for any feedback you might provide!

The "lightweight" nature of OpenBSD is a matter of perspective - if you are happy with OpenBSD's feature set, then it's a plus. On the other hand, FreeBSD has a lot of additional features, including ZFS, which may be of interest. The last I checked, FreeBSD was more performant in various benchmarks, particularly regarding multi-core performance.
FreeBSD has the same roots as OpenBSD but the former has a “compatibility” focus whereas the latter has the security focus. Having a background in security, the choice was obvious for me. But each person/org should decide based on their needs. Haven’t had any issues running it on all major hardware (Dell, HP, Lenovo, Apple, etc) the UI isn’t as pretty as macOS on Desktop, but it runs Firefox & Chrome, etc. so you can do everything you need. If you have an older Lenovo or Mac lying around collecting dust, dive in!
OpenBSD is security focused while FreeBSD will remind you of older X-Windows workstations.
FreeBSD is a heavier, more capable system, suitable for large servers. It's got its own virtualization platform (bhyve), an LXC-ish container system (jails), native ZFS, dtrace, Linux emulation, and a bunch more. It makes for a decent workstation and has pretty decent hardware support.
NetBSD is small and simple. It's a lot like an old-school UNIX. It makes a decent platform for small services. I run bind and dhcpd on a NetBSD machine. The source code is very pleasant to read. It uses the pkgsrc software repository. It's my preferred platform for writing POSIX code.
OpenBSD still carries much of the general feel of NetBSD and can fill a similar niche on a network, but the security focus stands out in their documentation, subprojects (OpenSSH, LibreSSL, OpenNTPD, etc.), APIs (see pledge(8)), and policies. It makes for a great firewall. I'd say it also requires the most know-how.
All of them have excellent documentation (especially compared to Linux distros) and the base system is developed alongside the kernel, giving you a very consistent experience compared to Linux distros where everything is developed in isolation. If you write C, it's worth keeping a BSD system around just for the manpages and to make sure you're not letting Linuxisms creep into your codebase.
