Matrix packages (mautrix-*, matrix-continuwuity) only exist in
nixpkgs-unstable, not in nixpkgs 24.05 stable. This commit updates
all module defaults and references to use pkgs-unstable.
Changes:
- Add pkgs-unstable to module function signatures (4 modules)
- Update package option defaults from pkgs.* to pkgs-unstable.*
- Configure pkgs-unstable in flake.nix to permit olm-3.2.16
- Add VM config permittedInsecurePackages for olm (mautrix dependency)
The olm library is deprecated with known CVEs but required by mautrix
bridges. This is acceptable for testing; production should migrate to
newer cryptography implementations when available.
This maintains our stable base system (NixOS 24.05) while using
unstable only for Matrix ecosystem packages under active development.
- Add ops-jrz1-vm NixOS configuration to flake outputs
- Create hosts/ops-jrz1-vm.nix with VM-specific settings
- Configure test credentials (root:test) for local testing
- Import all Matrix platform modules for validation
- Enable VM testing workflow to catch deployment issues early
The VM config uses specialArgs to pass pkgs-unstable for Matrix
packages while keeping the base system on nixpkgs 24.05 stable.
