Pre-commit needs to be fixed in order for this to get merged.

@mtelka FYI - no issue associated with this PR, which would help in identifying the problem being fixed. Given Salt Core dropped support for native minions Solaris 10 and 11 in 3005, wondering about this PR. Presume pip installing Salt on Solaris or Illumos, or equivalent. Also. note minimum Python version 3.10 is supported by 3006.x and above (work on going to get Py 3.12 support but unfinished). The docs stating that haven't been released yet due to staff leaving (months late on that)

This fixes #7.

We do have salt packaged for OpenIndiana. However I'm not sure how it works.

Would you mind fixing the pre-commit failures please?

Who? Me?

I'm very sorry, but I've no idea how to fix that. I do see two failures there:

Failure 1:

Check python modules for appropriate copyright headers.......................Failed
- hook id: check-copyright-headers
- files were modified by this hook

Updated the copyright header on .pre-commit-hooks/copyright-headers.py
Updated the copyright header on noxfile.py
Updated the copyright header on .pre-commit-hooks/check-changelog-entries.py
Updated the copyright header on src/pytestsysstats/__init__.py
Updated the copyright header on .pre-commit-hooks/sort-pylint-spelling-words.py
Updated the copyright header on setup.py
Updated the copyright header on docs/conf.py
Updated the copyright header on tests/functional/test_syststats.py
Updated the copyright header on src/pytestsysstats/plugin.py
Updated the copyright header on tests/conftest.py

This is something apparently not related to this change because it lists files that are not touched by this PR.

Failure 2:

black........................................................................Failed
- hook id: black
- exit code: 1

Traceback (most recent call last):
  File "/home/runner/.cache/pre-commit/repozy7ddl98/py_env-python3.9/bin/black", line 8, in <module>

ImportError: cannot import name '_unicodefun' from 'click' (/home/runner/.cache/pre-commit/repozy7ddl98/py_env-python3.9/lib/python3.9/site-packages/click/__init__.py)

Again, I do not understand how is this related to my change.

So in short, it looks like both issues were there even before my PR.

@mtelka Pre-commit failures are probably due to aging of the various pre-commit tests. Classic case of Software Rot over time. However Pottery Barn rules apply, touch and break it, you own it :D . Take it as an opportunity to learn.
Note, normally the Salt Core team would assist but with the recent reduction in size and for a platform no longer supported (Solaris), you should at least make the first attempt to get pre-commit working, if it helps I recently updated pre-commit for pytest-shell-utilities, that might be a good case for cut and paste, etc., at least for recent versions of tools used.
