Hi! This is the friendly automated conda-forge-linting service.

I just wanted to let you know that I linted all conda-recipes in your PR (recipe) and found it was in an excellent condition.

This is not needed right now but should alleviate bootstrapping problems caused by conda-build accidentally importing conda straight from SRC_DIR (working directory) during the build and host activation steps (which happen to use python -m conda ... to generate the shell code that is then evald; python -m injects the working directory in sys.path).

So no need to merge this, but we could have it in mind for next releases in which the dependencies of the new conda version differ from the conda version available in the base environment from which conda-build runs off.

This can technically apply to not just conda, but every package that happens to be imported during the conda activate code paths, as available in base. As of conda 23.1, these are:

• __distutils_hack
• conda
• cython_runtime (???)
• pkg_resources
• ruamel.yaml
• setuptools
• toolz (tlz)
• tqdm

Note: we might want to optimize which modules are imported in the shell activation paths, for better performance.
