You don't have to go to that extreme. Although, /usr/local should be its own partition for the wxallowed, and /var/log should be its own to keep some nasty logging from screwing everything up. I have a standard /, /home, /tmp, /usr, /usr/local, /var, /var/log. I also am a heretic so I also do /opt.

It actually isn't that hard. I do wish OpenBSD had a more robust filesystem. I switch to FreeBSD when I need a server with lots of storage.

[edit] the vultr install of OpenBSD only has / and /usr/local
