I've been evaluating bootc and other declarative options after all the nixpkgs/nix leadership failures and having dozens of hours of packaging improvement work ignored by individual package maintainers and entire SIGs, and i'm quite disappointed that they've been completely uninterested in providing any declarative solution for per-host "state" with bootc systems -- having to set up a boot Dockerfile (sorry daddy shadowman i meant Containerfile!!!) and then also use Ansible and/or cloud-init on top of that to set up a new host is just a complete non-starter when NixOS can handle both in one language framework and development environment even if that framework is heterodox jank that everyone outside of nixpkgs resents.
