Multiple packages installing the same file

Users

How is conda supposed to handle multiple packages installing the same file? With rpm it would result in an error about conflicting files, but conda (or at least micromamba) seems to just emit a warning:

The following files were already present in the environment:
    - lib/liblzma.so.5

And it is installed by two different packages:

liblzma-5.8.1-hb9d3cd8_0.json:        "lib/liblzma.so.5",
liblzma-5.8.1-hb9d3cd8_0.json:        "lib/liblzma.so.5.8.1"
liblzma-5.8.1-hb9d3cd8_0.json:                "_path": "lib/liblzma.so.5",
liblzma-5.8.1-hb9d3cd8_0.json:                "_path": "lib/liblzma.so.5.8.1",
xz-5.2.6-h166bdaf_0.json:        "lib/liblzma.so.5",
xz-5.2.6-h166bdaf_0.json:        "lib/liblzma.so.5.2.6",
xz-5.2.6-h166bdaf_0.json:                "_path": "lib/liblzma.so.5",
xz-5.2.6-h166bdaf_0.json:                "_path": "lib/liblzma.so.5.2.6",

This should be fixed once Extend xz_split scope by xhochy · Pull Request #1021 · conda-forge/conda-forge-repodata-patches-feedstock · GitHub has been merged. Now liblzma ensures that it is only co-installed with the same version of xz where the files are split correctly.
