Add support for specifying a directory other than /tmp for installation execution

[edlitmus]

What does this PR do?

Adds an option to specify something other than /tmp for installation execution.

What issues does this PR fix or reference?

Systems that have been hardened to CIS-2 benchmarks should have /tmp and /var/tmp mounted with the noexec option. This causes installations to fail when trying to execute anything from /tmp.

New Behavior

Using the new option allows installations to proceed as expected. An example using the ubuntu user home directory:

bash /home/ubuntu/bootstrap-salt.sh -X -U -A localhost -T /home/ubuntu onedir "$SALT_VERSION"

@edlitmus You need to refresh, released v2024.12.12 today, fix the lint errors by running the following in your work directory pre-commit install, this way you will catch lint errors, etc when you git commit.

And lastly, you need to add tests to ensure your changes to code are tested.

Thanks, I refreshed and fixed the lint errors.

Any guides on adding tests for this? I'm not sure where to start on that.

@edlitmus Adding tests using pytest, similar to Salt itself, except don't have to use nox. Take a look at https://github.com/saltstack/salt-bootstrap/blob/develop/tests/integration/test_installation.py and also Salt test and pytest documentation

• https://docs.saltproject.io/en/latest/topics/development/tests/index.html
• https://docs.saltproject.io/en/latest/topics/tutorials/writing_tests.html
• https://docs.pytest.org/en/stable/
• https://www.tutorialspoint.com/pytest/index.htm

Lastly, if you add a feature to Linux, you cannot ignore Windows, needs to be added there too, that is, bootstrap-salt.ps1 needs updating too.

@dmurphy18 Sorry for the delay on this, I was taking time off, but I did some digging into the Windows side of this, and it doesn't look like the options for the Windows script are a match for the shell script. Also, I don't think it makes sense to add the same feature to the Windows script as I do not believe that noexec exists for NTFS, so it wouldn't be something that would be required for the installation on Windows systems.

As for the tests, I still need to look into how to add something to do validations.
