So the project is alive and it seems more active than previously.
I love FreeBSD. But I reluctantly had to migrate one of my home servers to Ubuntu Server because I needed Docker support as well as ZFS. Ubuntu Server, compared to FreeBSD, is a complete clusterfuck of an OS. And I regret the effort I spent migrating.
My current setup for Docker (Podman really in my case):
Proxmox -> Linux VMs -> Podman containers inside Linux VMs
My plan: FreeBSD's bhyve hypervisor -> Linux VMs -> Podman containers inside Linux VMs
So basically just ditching Proxmox for FreeBSD/bhyve. Then at long last I'll be, again, systemd-free.
