[2.0] Site-wide configuration?

[sleiner]

In PDM 2.0, there are two "layers" of configuration as far as I see (ranked by descending priority):

• Project Configuration (which is, of course, project-specific)
• Home Configuration (which is user specific)

I'm proposing to add a third layer, located at platformdirs.site_config_dir("pdm") which serves as the lowest-priority layer.

Why would this be helpful?

For multi-user setups, it would make sense for the system administrator to set some default settings, e.g. the default Python path or a potential PyPI mirror.

What do you think of this?

SGTM, but it will be read-only from CLI

Read-only from CLI seems sensible 👍🏻

Should I convert this to an issue?

Sure
