We use OpenBSD for our VPSes on Hetzner, bare metal (for security focussed clients) and older (but still good) hardware in our Home Lab. OpenBSD is excellent on older (no longer supported by Cupertino) Apple hardware. We have an Intel Mac Mini Cluster with near-perfect uptime. If you need to run any kind of server (Web, Mail, DNS, NFS, Database) where you need stability & security, look no further. Some learning curve, but totally worth it.
I want to use OpenSMTPD so badly, but it doesn't have proper support for authentication via LDAP (at least, as far as I can tell). It insists on reading plaintext passwords from the LDAP server, rather than BINDing as the user in question.
What's the situation with Broadcom wifi on your intel macs?
We've run into instability issues with the newer Linux kernels (starting with 6.x, I think) and have had to stop upgrading.
I use OpenBSD among Hyperbola GNU/Linux, soon to be rebased from a deblobbed OpenBSD 7.0 hard fork. IT's dumb easy to setup too. Also, I daily use nvi, oksh, oed (a portable ed for GNU/Linux) among Xenocara and CWM, and this way the environment it's almost the same as OBSD but with a GNU/Linux kernel.
Have 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!
