my big issue when I looked into it was the default filesystem was quite an antiquated design that would lose or corrupt data in a powercut or unexpected shutdown. Last I checked many of the devs have fairly elaborate uninterruptable power supplies to deal with this.

A lot to like about openBSD; doas is my daily driver on linux, openbsd man changes are incredible, but I'm not going to mess about recovering disks just because I forgot to plug my laptop in.
