### Bug Description When installing the stage package `python3.8-venv`, the `python3` symlink will be set (even though it is not a part of that package). OTOH, if installing `python3.8` instead (which is a dependency on `python3.8-venv`), that symlink won't be there. I can't put my finger on where that symlink comes from, but since these are stage packages, it shouldn't be from the maintainer scripts. Plus, the fact that the symlink is there for the former pkg but not the latter, is also concerning ### To Reproduce Pack the rock. First with the yaml provided below. Then change `python3.8-venv` to `python3.8`, and pack again ### Environment Latest rockcraft ### rockcraft.yaml ```shell name: app base: ubuntu@20.04 version: '0.1' summary: rock description: | some rock license: GPL-3.0 platforms: amd64: parts: python-flask: plugin: nil stage-packages: - python3.8-venv ``` ### Relevant log output ```shell n/a ```
