I just got my nitrowall today! I had to remove the SSD to be able to boot from USB and install Vyos as I found no way to change the default boot device. After this small workaround vyos is running sucesfully.... BUT changing configurations is painfully slow. Just "configure" and then "show" takes 6 seconds while unionfs-fuse will consume 50% or so of a CPU. It was not so slow when I was running on a KVM guest on proxmox. Will need to see if I find a solution as this performance makes the solution unusual to work with via Terraform - refresh times out.
