The other day, I used FreeBSD on a Raspberry Pi card to get a redundant DHCP server and DNS resolver working together with an OpenBSD server. It works great. But another FreeBSD server is available and I don’t really need yet another gadget powered on. So I moved both the DHCP and DNS services to this machine. While I was there, I took the opportunity to put them into their own jails. Because, you know, privilege escalation…

But even if the OpenBSD installer is straight forward, deploying tens of VM takes some time. So I set up an automated environment that provides fast and (nearly) finger-less deployment.
