Sometimes you just need that old version. So I installed it. FreeBSD 9.3 Sorry, but this article is light. I stopped taking notes after a bit…. We created a VM via VMware, put FreeBSD 11.1 on it, over ZFS. Then install iocage. This is what it looked like: What did it just install? This: $

I have several old devices. Upgrading them is either impossible, they are unsupported, or I can’t be bothered upgrading the. Access is only via a dedicated VLAN within my home network.
