Summary

Tracking issue for installation-related settings supported by the pnpm CLI that the Rust port (pacquet) does not yet support. This was produced by diffing pnpm's Config type (config/reader/src) against pacquet's config crate (pacquet/crates/config/src/lib.rs), its CLI args, and the rest of the workspace.

Scope is limited to pacquet's current command surface: install, add, update, remove. Settings that only affect publish/run/exec/dlx/audit are excluded.

Pacquet already covers a large surface (hoisting, nodeLinker, dedupe-*, peer resolution, store/virtual-store layout, minimumReleaseAge, trustPolicy, overrides, packageExtensions, patchedDependencies, allowBuilds, supportedArchitectures, fetchRetry*, catalog resolution, etc.). The gaps below are what remain.

Lockfile

• lockfileOnly / --lockfile-only — resolve + write lockfile without linking (done in feat(pacquet): port lockfileOnly setting #12046)
• lockfileDir — custom lockfile location
• sharedWorkspaceLockfile — toggle for single root lockfile
• useGitBranchLockfile, gitBranchLockfile, mergeGitBranchLockfiles, mergeGitBranchLockfilesBranchPattern — per-branch lockfiles
• frozenLockfile as a config-file/env setting (currently only a CLI flag)

Resolution / versions

• resolutionMode (highest / time-based / lowest-direct)
• registrySupportsTimeField
• allowedDeprecatedVersions
• updateConfig.ignoreDependencies
• peerDependencyRules (ignoreMissing, allowAny, allowedVersions)

Builds / scripts / hooks

• ignoreScripts
• enablePrePostScripts, scriptShell, syncInjectedDepsAfterScripts
• onlyBuiltDependencies / onlyBuiltDependenciesFile / neverBuiltDependencies (currently silently ignored; pacquet uses allowBuilds/dangerouslyAllowAllBuilds instead)
• strictDepBuilds
• .pnpmfile.cjs hooks (pnpmfile, globalPnpmfile, enablePnpmfile, ignorePnpmfile) — pacquet does not run pnpmfiles yet

Patching

• allowUnusedPatches (and allowNonAppliedPatches)
• patchesDir

Store / modules

• virtualStoreOnly
• stateDir
• strictStorePkgContentCheck
• enableModulesDir
• preferSymlinkedExecutables

Network (currently hardcoded defaults in pacquet, not configurable)

• networkConcurrency, fetchingConcurrency, maxSockets
• fetchTimeout, fetchWarnTimeoutMs, fetchMinSpeedKiBps
• userAgent, npmrcAuthFile

Catalogs

• catalogMode
• cleanupUnusedCatalogs

Workspace

• ignoreWorkspaceCycles / disallowWorkspaceCycles
• includeWorkspaceRoot

Save behavior (add/update)

• savePrefix
• saveWorkspaceProtocol
• savePeer
• saveCatalogName

Manifest / engine

• engineStrict, nodeVersion (engine-strict gating during install)
• configDependencies

Notes

• enablePnp is not a separate setting in either implementation — pnp is a nodeLinker value, which pacquet already accepts.
• The network settings exist as internal constants in pacquet (e.g. default_network_concurrency()) but aren't user-configurable.
• Some items (pnpmfile hooks, onlyBuiltDependencies) are already acknowledged as TODOs in pacquet's own source comments.
