| Also note that with [pure evaluation mode](@docroot@/command-ref/conf-file.md#conf-pure-eval), accessing files not so easily accessed via relative paths is often prohibited anyways. |

Reworded, and move from release notes to the settings description, where it will be read more on an ongoing basis.

Motivation
Fixes #8738
Context
Besides the direct user benefit of having this lint, this reduces the evaluator's usage of
rootFS, which also gets us closer to #9549.Review with whitespace disabled.
