The directory name was tailscale-subnet-router but networking.hostName
was already tailscale-router, causing a mismatch that confused scripts
comparing directory paths against actual hostnames. Flake attribute
names (linode/proxmox/lxc-tailscale-subnet-router) and .sops.yaml
anchors are unchanged — they describe the build type, not the hostname.
