One fix for lo up in a shell that exports only PATH. No configuration change is needed.

Fixed

• lo up with the v0.4.0 lo (core) binary created the kind cluster and then failed in the bootstrap step:

  Error: loading generator plugins: failed to load generator: unable to find plugin root - tried: ('<no value>'; homed in $KUSTOMIZE_PLUGIN_HOME), …
  [error] bootstrap: render failed for cilium

  Every addon that depends on cilium was skipped. lo doctor in the same shell reported ✓ KUSTOMIZE_PLUGIN_HOME=<project>/.kustomize.

  The cause: the binary set KUSTOMIZE_PLUGIN_HOME for its bash children and for the lo build render, but not for the kustomize child of the addon render that bootstrap runs. The project .envrc exports the variable; a shell that exports only PATH does not. In that shell the child had no plugin home.

  The fix: one function decides the plugin home for every child of the binary. It returns the variable when the shell exports it, else <project>/.kustomize. The addon render, lo build, lo k8s, the registry TLS mint, the bash shim and lo doctor all read that function. lo doctor cannot report a home that the render does not use.

Who is affected

A project that runs lo (core), or lo-full with LO_RENDER=exec, from a shell that does not export KUSTOMIZE_PLUGIN_HOME. The in-process render of lo-full reads no plugin home and was not affected. A shell that exports the variable was not affected.

Upgrade

1. Install the binary: bash lo-install.sh, or unpack lo-<os>-<arch>.tar.gz (lo-full-<os>-<arch>.tar.gz for the in-process build) from the release. A project that pins lo through lo toolchain install bumps github.com/kernpilot/lok8s in .bin/b.yaml to v0.4.1 and runs b install.
2. Run lo up again. The addons that were skipped are applied.

Assets

The same set as v0.4.0: for linux and darwin, amd64 and arm64, lo-<os>-<arch>.tar.gz, lo-full-<os>-<arch>.tar.gz, kustomize-secret-<os>-<arch>, lochat-<os>-<arch>, plus lok8s-v0.4.1.tar.gz (the framework tree), lo-install.sh and checksums.txt.
