- Host-local files: the installer writes `hosts/local-<hostname>.nix` and `hosts/local-<hostname>-hardware.nix` on the target. These are ignored by git. When syncing, exclude them to avoid deletion:
`rsync -a --exclude 'hosts/local-*.nix' --exclude 'hosts/*-hardware.nix' --exclude '.git' . admin@<vm>:/home/admin/nixos-sync`
