Linuxbrew on devpods needs sudo symlinks outside $HOME that vanish on restart, a weekly CI tarball to beat the on-create timeout, and about 2 GB on disk. This adds mise as a package manager that installs the same tools as pinned upstream release binaries, and a devpod-slim profile to try it alongside the existing devpod profile.

  • add mise as the first cascade manager, opt-in per package via a mise: backend spec (aqua: preferred, github: when aqua lacks the tool)
  • render mise packages into ~/.config/mise/conf.d/20-packages.toml at "latest"; pin them in a committed, generated .chezmoitemplates/mise-packages.lock (version, URL, sha256 for linux-x64 and linux-arm64)
  • merge those pins into the machine's global ~/.config/mise/mise.lock with a modify_ template instead of overwriting it: add missing tools, take newer or changed repo entries, keep newer local versions, never touch or remove entries the repo does not manage (toolchains, mise use -g)
  • add scripts/mise-lock to regenerate the pins from packages.yaml; --bump re-resolves every latest, --force-overwrite resets a machine's lock to the repo's
  • add run_onchange_16-install-packages-mise: installs a pinned mise via mise.run, runs mise install --locked on the managed tools, links ~/.local/bin/fish for the login shell, prunes superseded versions
  • add optional mise_version and mise_opts package fields; install atuin and yazi from musl builds and hold tree-sitter at 0.25, since their gnu builds need glibc 2.38+ and devpods run Debian 12 (2.36); the install script warns when ldd cannot resolve a managed binary
  • add the devpod-slim profile and a devpod profile flag so both devpod profiles share the bootstrap and shell scripts; Linuxbrew setup now runs only for brew devpods
  • classic devpod: stamp the Brewfile hash into the Homebrew prefix so a freshly restored tarball skips brew bundle and brew bundle cleanup; stream the tarball download into extraction; drop translations, headers, static libs, and doc/info pages from the tarball (man pages kept)
  • run the cache workflow on pull requests against the PR branch, with a new devpod-slim apply job; publish only from main
  • run mise activate uncached; the cached output replayed a stale PATH snapshot
  • move ~/.local/bin ahead of mise activate in fish so a mise installed there is found
  • document the add/upgrade/reset workflow in AGENTS.md and the add-package skill

Existing profiles render identical package lists; the mise script is a no-op for them and their mise lock is not managed.

Validation

  • rendered brew and pacman package lists diffed against main for macos-work, devpod, arch-desktop
  • fresh devpod, DOTFILES_PROFILE=devpod-slim chezmoi init --apply
  • login shell, interactive and non-interactive tool resolution
  • lock merge: no-op, local mise use -g, repo newer, local newer, missing lock, mise reformatting
  • ldd check over every managed binary on Debian 12
  • lock merge when the repo changes a version spec (tree-sitter latest -> 0.25)
  • classic devpod pod on this branch: login shell, tools, stamp written
  • trimmed CI tarball on a devpod: stamp match skips both brew passes, man and brew bundle check pass, no dangling symlinks
  • --force-overwrite on a devpod, and its refusal on a non-mise profile
  • stray unmanaged global mise config does not break the install
  • scripts/mise-lock rerun without --bump leaves the pins unchanged

Summary by CodeRabbit

  • New Features
    • Added a devpod-slim profile that uses Mise to manage packages, alongside the existing Linuxbrew-based profile.
    • Expanded package support with Mise-managed tools and lockfile-based installs.
    • Added a workflow to verify slim Linuxbrew builds and publish them only from the main branch.
  • Bug Fixes
    • Improved Linuxbrew archive extraction with a fallback path that preserves the existing installation if an update fails.
    • Updated shell setup to find Fish and activate Mise more reliably.

📝 Walkthrough

Walkthrough

The changes add mise package selection and locked installation, define a devpod-slim profile, and update devpod setup scripts. The Linuxbrew workflow now builds from pull request branches, verifies devpod-slim, and publishes only from main after both jobs pass.

Changes

mise-backed devpod-slim

Layer / File(s) Summary
Profile and package selection
.agents/skills/add-package/SKILL.md, AGENTS.md, home/.chezmoidata/packages.yaml, home/.chezmoidata/profiles.yaml, home/.chezmoiignore.tmpl, home/.chezmoitemplates/cascade-filter, home/dot_config/mise/conf.d/20-packages.toml.tmpl
The package cascade puts mise before Homebrew. Package entries add mise backends, and devpod-slim enables mise. The generated mise tools configuration uses package versions and options from the package data.
Locked mise installation and shell integration
AGENTS.md, home/run_onchange_16-install-packages-mise.sh.tmpl, scripts/mise-lock, home/dot_config/fish/conf.d/zz_01_paths.fish.tmpl, home/run_onchange_59-configure-fish-shell.sh.tmpl, home/run_onchange_60-install-fisher.sh.tmpl
The installer bootstraps mise, installs declared tools with mise install --locked --yes, links Fish when available, checks executables for missing shared libraries, and prunes superseded versions. The lock script generates repository pins for Linux x64 and arm64. Fish setup adds ~/.local/bin to PATH and sources mise activation output directly.
Profile-aware devpod setup
home/run_after_90-devpod-shell.sh.tmpl, home/run_before_00-devpod-bootstrap.sh.tmpl, home/run_onchange_10-install-packages-homebrew.sh.tmpl, home/dot_local/bin/executable_devpod-linuxbrew-fetch
Devpod scripts now check profile settings instead of matching a profile name. Linuxbrew setup runs only when brew is enabled. The Brew installer uses a Brewfile hash to skip unchanged bundle work, and the fetch script falls back to downloading the archive when streamed extraction fails.
Build, verify, and publish
.github/workflows/devpod-linuxbrew-cache.yml
The workflow builds from the pull request head and creates an archive that excludes selected files while retaining man pages. A devpod-slim job checks managed executables for missing shared libraries and runs selected tool commands. Publishing waits for both jobs and runs only for non-pull-request events on main.

Before / after behavior

  • observed — Modified behavior in AGENTS.md: The profile documentation adds mise to the package-manager list and describes the Uber devpod bootstrap and login-shell scripts.
  • observed — Modified behavior in AGENTS.md: The profile table adds devpod-slim, using the mise package manager with core, dev, and ai tags, work enabled, and decryption and backup disabled.
  • observed — Modified behavior in AGENTS.md: The package-management documentation adds mise as an opt-in manager and places it first in the cascade, before Homebrew. It documents devpod-slim package selection, generated platform-specific lock pins, merging repository pins into the local lockfile while preserving local upgrades and unmanaged entries, and running locked installs. It also adds package-list and upgrade workflows, local mise usage guidance, glibc compatibility options and warnings, and a force-overwrite reset procedure.
  • observed — Modified behavior in AGENTS.md: The install-script list adds the mise installer and describes its pinned package versions, pinned mise installation, and Fish executable link.

Comment @coderabbitai help to get the list of available commands.

- add `mise` as the first cascade manager: packages with a `mise:` backend
  (aqua preferred, github fallback) install as prebuilt release binaries
- render those packages into ~/.config/mise/conf.d/20-packages.toml and pin
  them in a committed, generated mise.lock (version, URL, sha256 per
  platform for linux-x64 and linux-arm64)
- add scripts/mise-lock to regenerate the lock from packages.yaml;
  --bump re-resolves every "latest" for upgrades
- install with `mise install --locked` scoped to the declared tools,
  bootstrap a pinned, checksummed mise into ~/.local/bin, link
  ~/.local/bin/fish as a stable login shell, prune superseded versions
- add the devpod-slim profile (same tags as devpod, mise instead of brew)
  and a `devpod` profile flag so both share the bootstrap and shell
  scripts; Linuxbrew setup now runs only for brew devpods
- put the pinned mise and the shims dir on PATH for mise profiles

Why: Linuxbrew on devpods needs sudo symlinks outside $HOME that vanish on
restart, a weekly CI tarball to beat the on-create timeout, and about 2 GB
on disk. The same 34 tools as pinned binaries take about 590 MB, live under
$HOME, and a fresh devpod-slim apply finishes in seconds.
- move the repo pins to .chezmoitemplates/mise-packages.lock and merge
  them into ~/.config/mise/mise.lock with a modify_ template: add missing
  tools, take newer or changed repo entries, keep newer local versions,
  never touch or remove entries the repo does not manage
- add scripts/mise-lock --force-overwrite to reset a machine's lock to
  the repo's and reinstall managed packages
- install mise with the standard mise.run installer, still pinned
- drop the shims PATH entries; move ~/.local/bin ahead of mise activate
  in fish so a mise installed there is found, and revert the bash change

Why: one mise serves both managed packages and local use (toolchains,
mise use -g), and they share a global lockfile. Overwriting it from the
repo dropped local entries on every apply; merging keeps both.

Comment thread home/dot_config/mise/modify_mise.lock
- add mise_version and mise_opts package fields, rendered into the
  mise drop-in as a version spec and backend options
- install atuin and yazi from their musl builds and hold tree-sitter
  at 0.25; their gnu builds need glibc 2.38/2.39, devpods have 2.36
- take the repo lock entry when its version spec changed, so a pin like
  latest -> 0.25 is not overridden by a newer local version
- warn after install when ldd cannot resolve a managed binary

Why: atuin, yazi, and tree-sitter installed on devpod-slim but failed to
start with missing GLIBC_2.38/2.39 symbols.
Why: the activate output embeds `set -gx PATH` with the PATH of the shell
that generated it, so the cached copy replayed a stale PATH snapshot into
every new shell, dropping later changes made before activation.
- stamp the Brewfile hash into the Homebrew prefix after bundle and
  cleanup succeed; a devpod whose restored tarball carries a matching
  stamp skips both brew passes
- stream the tarball download into extraction, falling back to
  download-then-extract on failure
- leave translations, headers, static libraries, and doc/info pages out
  of the tarball; keep man pages, which fish uses for completions
- build and verify pull requests from their own branch (devpod, plus a
  new devpod-slim apply job with an ldd check); publish only from main

Why: on a fresh classic devpod, brew bundle and cleanup re-verified a
tree the tarball had just restored, about 5-7s, and roughly 12% of the
tarball's files were never used at runtime. The cache workflow also
always applied main, so no PR was ever tested before landing.
Why: the keep-local-newer rule only applied when both versions were
strict semver, so tmux 3.7c in the repo lock overwrote a locally
upgraded 3.7d. Non-semver versions now compare the numeric prefix with
semver, then the suffix.

🟡 Medium risk · Adds a mise-based devpod profile and changes package installation and bootstrap workflows.

Adds mise as a cascade package manager with a devpod-slim profile, lock-based pinning, and intelligent merge logic that preserves local versions and respects unmanaged tools. Non-semver version handling has been fixed to keep newer local builds. No open issues remain.

✅ 1 closed
✅ Edge Case: Non-semver versions (tmux 3.7c) bypass keep-local-newer rule

📄 home/dot_config/mise/modify_mise.lock:19 📄 home/dot_config/mise/modify_mise.lock:27-31 📄 home/.chezmoitemplates/mise-packages.lock:436
The merge keeps a newer local version only when both versions match $semver. When either one fails the regex, $take stays true and the repo entry always replaces the local one. That happens for the managed tmux pin 3.7c (aqua:tmux/tmux-builds). So if a machine runs mise upgrade and gets tmux 3.7d, the next chezmoi apply sets the lock back to 3.7c. That breaks the rule in the header comment ('local version newer -> keep local') and the AGENTS.md promise that mise upgrade is safe. One fix is to leave differing non-semver versions alone unless the repo entry is new. Another is to compare such versions with a looser rule, for example by stripping a trailing letter suffix before semverCompare.
