Fix bug where new hosts were added outside of nixosConfigurations block
instead of inside it.
Issues fixed:
1. Pattern was looking for "packages =" but actual text is "packages = forAllSystems"
2. Replacement was putting new entry AFTER closing brace instead of BEFORE
3. testvm01 was at top-level flake output instead of in nixosConfigurations
Changes:
- Update pattern to match "packages = forAllSystems"
- Put new entry BEFORE the closing brace of nixosConfigurations
- Move testvm01 to correct location inside nixosConfigurations block
Result: nix flake show now correctly shows testvm01 as NixOS configuration

Fix error "500 can't upload to storage type 'zfspool'" by using "local"
storage pool for cloud-init disks instead of the VM's storage pool.
Cloud-init disks require storage that supports ISO/snippet content types,
which zfspool does not. The "local" storage pool (directory-based) supports
this content type.

Fix OpenTofu error where static IP and DHCP branches had different object
structures in the subnets array. Move conditional to network_config level
so both branches return complete, consistent yamlencode() results.
Error was: "The true and false result expressions must have consistent types"
Solution: Make network_config itself conditional rather than the subnets
array, ensuring both branches return the same type (string from yamlencode).

Remove mention of .generated/ directory and clarify that cloud-init.tf
manages all cloud-init disks, not just branch-specific ones.

Replace SSH upload approach with native proxmox_cloud_init_disk resource
for cleaner, more maintainable cloud-init management.
Changes:
- Use proxmox_cloud_init_disk for all VMs (not just branch-specific ones)
- Include SSH keys, network config, and metadata in cloud-init disk
- Conditionally include NIXOS_FLAKE_BRANCH for VMs with flake_branch set
- Replace ide2 cloudinit disk with cdrom reference to cloud-init disk
- Remove built-in cloud-init parameters (ciuser, sshkeys, etc.)
- Remove cicustom parameter (no longer needed)
- Remove proxmox_host variable (no SSH uploads required)
- Remove .gitignore entry for .generated/ directory
Benefits:
- No SSH access to Proxmox required
- All cloud-init config managed in Terraform
- Consistent approach for all VMs
- Cleaner state management

Implement dual improvements to enable efficient testing of pipeline changes
without polluting master branch:
1. Add --force flag to create-host script
- Skip hostname/IP uniqueness validation
- Overwrite existing host configurations
- Update entries in flake.nix and terraform/vms.tf (no duplicates)
- Useful for iterating on configurations during testing
2. Add branch support to bootstrap mechanism
- Bootstrap service reads NIXOS_FLAKE_BRANCH environment variable
- Defaults to master if not set
- Uses branch in git URL via ?ref= parameter
- Service loads environment from /etc/environment
3. Add cloud-init disk support for branch configuration
- VMs can specify flake_branch field in terraform/vms.tf
- Automatically generates cloud-init snippet setting NIXOS_FLAKE_BRANCH
- Uploads snippet to Proxmox via SSH
- Production VMs omit flake_branch and use master
4. Update documentation
- Document --force flag usage in create-host README
- Add branch testing examples in terraform README
- Update TODO.md with testing workflow
- Add .generated/ to gitignore
Testing workflow: Create feature branch, set flake_branch in VM definition,
deploy with terraform, iterate with --force flag, clean up before merging.

Add filesystem configuration matching Proxmox image builder output
to allow template2 to build with both `nixos-rebuild build` and
`nixos-rebuild build-image --image-variant proxmox`.
Filesystem specs discovered from running VM:
- ext4 filesystem with label "nixos"
- x-systemd.growfs option for automatic partition growth
- No swap partition
Using lib.mkDefault ensures these definitions work for normal builds
while allowing the Proxmox image builder to override when needed.

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.

Implements Phase 2 of the automated deployment pipeline.
This commit adds a Python CLI tool that automates the creation of NixOS host
configurations, eliminating manual boilerplate and reducing errors.
Features:
- Python CLI using typer framework with rich terminal UI
- Comprehensive validation (hostname format/uniqueness, IP subnet/uniqueness)
- Jinja2 templates for NixOS configurations
- Automatic updates to flake.nix and terraform/vms.tf
- Support for both static IP and DHCP configurations
- Dry-run mode for safe previews
- Packaged as Nix derivation and added to devShell
Usage:
create-host --hostname myhost --ip 10.69.13.50/24
The tool generates:
- hosts/<hostname>/default.nix
- hosts/<hostname>/configuration.nix
- Updates flake.nix with new nixosConfigurations entry
- Updates terraform/vms.tf with new VM definition
All generated configurations include full system imports (monitoring, SOPS,
autoupgrade, etc.) and are validated with nix flake check and tofu validate.

- README.md: Comprehensive documentation and examples
Removed files:
- vm.tf: Replaced by new vms.tf (archived as vm.tf.old, then removed)
