IncusOS lifted three weeks ago the main limitation I found in my initial exploration: the first ZFS pool can only use one drive, which made using the cheapest Hetzner servers a pain.

It is still limited compared to Proxmox; Proxmox claims to handle any drive failure easily, IncusOS recovers easily from failure of the "B" drive, but if the "A" drive fails, you need to install IncusOS to the new "A" drive.

Incus is amazing and I'm seriously considering IncusOS for my next iteration.
