It supports profile installation and upgrades, NixOS module export, no-install declaration writes, validation, documentation, and Docker-backed end-to-end tests. ChangesNix bootstrap packages
Priority: ➖ Normal Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🔵 Low · up to The new export command may expose an incorrect generated documentation source link, which can misdirect users seeking its implementation or reference. This is a bounded documentation issue but should be corrected before or shortly after merge. Suggested reviewers: Sequence Diagram(s)sequenceDiagram

Users can declare
"nix:ripgrep" = "latest"in[bootstrap.packages]and apply it through their normal Nix profile. The built-in manager supports use, apply, status JSON, and targeted upgrades, including top-level bootstrap. It preserves unrelated packages and leaves Nix sources, caches, trust, and profile rollback under Nix control.Adds
packages use --no-installfor all managers andpackages export --format nixto generate a deterministic NixOS module using the importing configuration’spkgs. Export respects merged configuration and selectors, requires no Nix executable, and rejects explicit sources, version pins, and invalid attributes before emitting output. Documentation covers profile installation and module import/rebuild workflows.Validation

Only the test copy’s dynamic loader and library path were adapted for the container.Verified installation, repeated apply without a new generation, registry shorthand, status JSON with store identity, and preservation of unrelated profile entries. A local flake with two Git revisions verified targeted upgrades and revision-pinned packages remaining pinned. Missing-source status and fresh default/XDG profiles verified read-only behavior; a failed install preserved the current generation.
The exported module was evaluated through the real NixOS module evaluator using the image’s pinned nixpkgs tree. Its selected
helloandjqpackages were built and executed; declaration removal, an empty manifest, and an invalid attribute were checked. This covers package operations and module consumption; it does not validate boot or system activation. Native operations were tested on Nix 2.35.2; macOS and older supported Nix releases were not exercised.AI-assisted — Tool: Codex; model: OpenAI/unavailable; version: unavailable.
Note
Medium Risk
New code executes the Nix CLI and mutates user profiles; export output is meant for NixOS evaluation, so incorrect attributes could break downstream configs despite validation and tests.
Overview
Adds Nix as a bootstrap package manager so
[bootstrap.packages]entries like"nix:ripgrep" = "latest"can be applied, checked, and upgraded via the user’snix profile(modern profile JSON, flakes/nix-command required). Status matches by flake source and attribute path; version pins, prune/absent removal, and unrelated profile entries are handled with the constraints documented in the new Nix guide.Also adds
mise bootstrap packages use --no-install(all managers) to record declarations without touching package managers, andmise bootstrap packages export --format nix, a read-only command that emits aenvironment.systemPackagesNixOS module from merged shorthandnix:entries only—rejecting explicit flake refs, version pins, and unsafe attributes before printing. CLI usage, man pages, site docs, e2e tests, and a Docker-based integration fixture cover export,--no-install, and real profile workflows.Reviewed by Cursor Bugbot for commit 69603e0.
