Check NixOS configurations / eval-hosts (pull_request) Failing after 11m29s
Three chunks of copy-pasted logic were drifting across scripts/*.sh: - codex-setup.sh and codex-maintenance.sh each carried an identical NIX_CONFIG bootstrap + ensure_nix_profile() -> scripts/lib/nix-bootstrap.sh - sync-host-keys.sh and prepare-host-key.sh each ran the same ssh-keygen/ssh-to-age nix-shell invocations -> scripts/lib/ssh-host-keys.sh (prepare-host-key.sh now also calls env.sh's nix_extra_opts before using them, closing a gap where it alone skipped the nix-cache reachability check env.sh exists for) - the "list nixosConfigurations attrNames" / "get one target's hostName" nix eval pattern was repeated across codex-setup.sh, codex-maintenance.sh, sync-host-keys.sh and create-proxmox-resource.sh (the latter twice, in its own --list and --host lookup) -> scripts/lib/nix-eval.sh, which also centralizes the --no-use-registries --no-accept-flake-config flag pair used on every such call Verified against the real flake/node config (nix is available here): create-proxmox-resource.sh --list for both --type lxc/vm, a full --dry-run create, and prepare-host-key.sh generating and cleaning up a real key/age-pubkey pair.
