Removing a bootstrap module from env leaves its resources on the machine. mise bootstrap unapply <ENV>… removes the managed files, directories, user services, and dotfile entries and edits contributed by one or more modules.

Remove the module from env in miserc.toml, keep its configuration file on disk, then preview and confirm cleanup:

mise bootstrap unapply ssh --dry-run
mise bootstrap unapply ssh

The command temporarily selects the named environments alongside the remaining selection, so it works after a module has been deselected. To remove several modules together, use mise bootstrap unapply ssh gpg.

Removal behavior

Mise compares the current configuration with and without the named environments; it does not maintain a history of applied resources. Keep the module declarations until cleanup is complete.

• Resources still declared present by the base configuration or another selected environment are preserved.
• Changed targets are skipped with a reason unless --force is supplied. Directories must be empty after the planned removals; unreadable directories and managed paths with an unexpected type are kept even with --force.
• Source files and configuration entries are preserved. Declarations of state = "absent" are not reversed.
• Removal requires confirmation. --yes, the global --yes, MISE_YES, and the yes setting approve it without a prompt; mise enables yes in CI.

Packages, repositories, and Compose projects require separate cleanup, with guidance printed for those declarations. Package pruning is not limited to one module. Other bootstrap sections, including system services, are outside the command's scope. --prompt-secrets supports configurations that require secret inputs.

Validation

The PR adds e2e coverage for previews, shared resources, changed targets, deselected environments, directory and path safeguards, confirmation, and repeated removal, plus unit coverage for environment argument forwarding and service-status classification.

Editorial validation: mise run lint-fix, cargo check --all-features, VitePress build, six TOML examples, 58 rendered internal links and anchors, and consistency between source help, the usage specification, CLI reference, and man page. Runtime tests were not rerun for the editorial update.

Closes the manual-cleanup gap described in #13437; builds on the module documentation in #13439.

Note

High Risk
Destructive filesystem and user-service removal with conservative planning, but mistakes or --force could delete user data; confirmation defaults to no in non-interactive runs.

Overview
Adds mise bootstrap unapply <ENV>… so you can tear down what a bootstrap module contributed after removing it from env, instead of hand-rolling dot unapply, state = "absent", and service removal.

Removal is planned by diffing desired state with vs. without the named environments (module config must stay on disk). It covers managed files, directories, user services, dotfiles, and edits, with --dry-run, interactive confirmation (or --yes / global yes), and --force for drifted targets. Shared resources from other envs are kept; non-empty or unreadable directories and wrong path types are skipped. Packages, repos, Compose, and system services are reported with separate cleanup guidance. The CLI re-selects missing envs via a child process (with safe handling of --cd / MISE_CD).

Docs, usage spec, man page, and e2e/unit tests accompany the new system/unapply planner and Config::without_environments.

Changes

The pull request adds mise bootstrap unapply <ENV>…. The command selects environments, plans selective resource removal, preserves shared or changed targets unless forced, and documents the command.

Bootstrap unapply

Layer / File(s)	Summary
Resource removal planning src/config/mod.rs, src/system/unapply.rs, src/system/user_services.rs	The system excludes selected environments from a base configuration, checks resource status, plans eligible removals, and reports skipped resources.
CLI selection and execution src/cli/bootstrap.rs	The CLI adds the command and flags, preserves forwarded arguments during environment selection, supports dry runs and confirmations, and executes removal plans.
Command contracts and validation mise.usage.kdl, src/cli/command_effects.rs, e2e/cli/test_bootstrap_unapply, src/cli/bootstrap.rs	The command is registered as destructive. Tests cover selection, shared resources, changed targets, force handling, dry-run output, directory handling, and repeated execution.
Command documentation docs/.vitepress/cli_commands.ts, docs/bootstrap.md, docs/cli/bootstrap.md, docs/cli/bootstrap/unapply.md, docs/public/llms.txt, man/man1/mise.1	Documentation describes usage, flags, preservation rules, supported resource sections, and delegated removal commands.

Confidence Score: 5/5

The PR appears safe to merge; the previously reported destructive-removal issues are resolved and the latest re-execution fix preserves the intended working directory.

Summary

Adds mise bootstrap unapply <ENV>… to remove resources contributed by deselected configuration environments while preserving shared or drifted resources.

• Plans removal by comparing configuration with and without the named environments.
• Covers managed files, directories, user services, dotfiles, and edits, with confirmation and dry-run support.
• Documents unsupported resource classes and adds end-to-end and unit coverage.
• The latest update prevents inherited MISE_CD from changing directories twice during child-process re-execution.

with_config_files must also recompute self.vars, self.tera_ctx, and each
bootstrap_config_maps entry’s tera_ctx from the retained config files, rather
than only removing config-file entries. Update this flow so retained resource
paths render using the base configuration values after declared_by_environment

In `@src/system/unapply.rs`:
- Line 268: Update the uncovered-section reporting loop to iterate over

removal commands are included.
- Around line 212-213: Update the ResourceAction match so
ResourceAction::Unknown is handled before the opts.force fallback, recording the
skipped removal with the “unexpected path type” reason and returning None; keep
forced removals for other action kinds unchanged.

🟠 Major · Exclude absent base declarations from the shared-resource sets. · unapply.rs:87-90

src/system/unapply.rs:87-90
🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Exclude absent base declarations from the shared-resource sets.

base_file_paths, base_directory_paths, and base_services include declarations with an absent state. If the remaining environment declares a resource absent and the removed environment declares it present, these sets filter the resource before removal planning. The installed resource then remains even though only the removed environment requires its presence.

Filter base requests to ManagedState::Present or a non-absent ServiceState before collecting their identities.

Proposed fix

-    let base_file_paths = paths(base_files.iter().map(|file| &file.path));
-    let base_directory_paths = paths(base_directories.iter().map(|directory| &directory.path));
+    let base_file_paths = paths(
+        base_files
+            .iter()
+            .filter(|file| file.state == ManagedState::Present)
+            .map(|file| &file.path),
+    );
+    let base_directory_paths = paths(

Instruction counts

Nothing was compared, and so nothing was gated. No series appears on both sides: either the base has no measurements recorded, or the two were measured on different runner classes, which are deliberately not comparable — counts shift between machine types by more than a real regression does.

New, nothing to compare against: env on jdx-perf-v1-ubuntu24.04-x64-mise-rust1.97.1-img5263c143, hook-env on jdx-perf-v1-ubuntu24.04-x64-mise-rust1.97.1-img5263c143, ls on jdx-perf-v1-ubuntu24.04-x64-mise-rust1.97.1-img5263c143, registry on jdx-perf-v1-ubuntu24.04-x64-mise-rust1.97.1-img5263c143, startup on jdx-perf-v1-ubuntu24.04-x64-mise-rust1.97.1-img5263c143
