Add systemd service that automatically bootstraps freshly deployed VMs with their host-specific NixOS configuration from the flake repository. Changes: - hosts/template2/bootstrap.nix: New systemd oneshot service that: - Runs after cloud-init completes (ensures hostname is set) - Reads hostname from hostnamectl (set by cloud-init from Terraform) - Checks network connectivity via HTTPS (curl) - Runs nixos-rebuild boot with flake URL - Reboots on success, fails gracefully with clear errors on failure - hosts/template2/configuration.nix: Configure cloud-init datasource - Changed from NoCloud to ConfigDrive (used by Proxmox) - Allows cloud-init to receive config from Proxmox - hosts/template2/default.nix: Import bootstrap.nix module - terraform/vms.tf: Add cloud-init disk to VMs - Configure disks.ide.ide2.cloudinit block - Removed invalid cloudinit_cdrom_storage parameter - Enables Proxmox to inject cloud-init configuration - TODO.md: Mark Phase 3 as completed This eliminates the manual nixos-rebuild step from the deployment workflow. VMs now automatically pull and apply their configuration on first boot. Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
