We don't have currently an OpenBSD server.
There could still be one on the hypervisor I've prepared some years ago with @fauve but it's probably old. OpenBSD 7.6 has been released 2024-10-08.
I really doubt the current OmniOS state of rOPS allow to deploy devserver role, but with some efforts the core role should be achievable.
Context: in troubleshoot section of ACME DNS, I wanted to suggest to use encrypt to generate a bcrypt hash, but that command is NOT available on FreeBSD.
That made me remember we had plan for an OpenBSD environment in the nasqueron-dev forest.
