[tjyang]

Is your feature request related to a problem? Please describe.
Since updating /opt/saltstack/salt/bin/pip is not recommend.

[me@rocky9t01a salt]$ /opt/saltstack/salt/bin/pip list |grep -i cherry
CherryPy           18.8.0

[notice] A new release of pip is available: 23.3.2 -> 24.3.1
[notice] To update, run: /opt/saltstack/salt/bin/../bin/python3.10 -m pip install --upgrade pip
[me@rocky9t01a salt]$ 

Describe the solution you'd like

• Without the pip upgrade notice to avoid pip upgrade.

[me@rocky9t01a salt]$ /opt/saltstack/salt/bin/pip list |grep -i cherry
CherryPy           18.8.0
[me@rocky9t01a salt]$

• Create a system pip.conf under /opt/saltstack path, that come with onedir pkg, to silence the pip upgrade notice. so following pip.conf under me user is not needed.

[me@rocky9t01a salt]$ cat ~/.config/pip/pip.conf
[global]
disable-pip-version-check = true
[me@rocky9t01a salt]$

Describe alternatives you've considered

• Advise user to create personal pip.conf.

[me@rocky9t01a salt]$ cat ~/.config/pip/pip.conf
[global]
disable-pip-version-check = true
[me@rocky9t01a salt]$
