Hetzner Cloud VPS Base Config
This is "device" type specific configuration for Hetzner's cloud VPS VMs.
Installation / Testing
Since the VPSes are qemu VMs, the systems can quite accurately be tested locally in qemu:
nix run '.#<hostname>' -- run-qemu --install
Once the system works locally, a fresh installation can be deployed to a new VPS:
HCLOUD_TOKEN=... nix run '.#<hostname>' -- deploy-system-to-hetzner-vps '<server-name>' '<server-type>'
Or deploy an existing image using deploy-image-to-hetzner-vps. The HCLOUD_TOKEN needs to be created in the cloud console, is specific to the cloud project, has to have write access, and can be revoked after the installation.
Alternatively, manually create a new server instance, boot it into rescue mode, and copy the installed image to it:
cat $image | zstd | ssh $newServerIP 'zstdcat >/dev/sda && sync'
If the system image is very large, even if it is mostly empty and with compression, the copy process can take quite a while. Declaring a smaller image size and expanding it on boot may be a workaround, but (since it depends on the disk partitioning and filesystems used) is out of scope here.
