Rescue or backup entire host

TL;DR Access PVE host root filesystem when booting off Proxmox installer ISO. A non-intuitive case of ZFS install not supported by regular Live Debian. Fast full host backup (no guests) demonstration resulting in 1G archive that is sent out over SSH. This will allow for flexible redeployment in a follow-up guide. No proprietary products involved, just regular Debian tooling.

Proxmox VE nag removal, scripted

Proxmox VE nag removal, manually

TL;DR Brief look at what exactly brings up the dreaded notice regarding no valid subscription. Eliminate bad UX that no user of free software should need to endure.
