I don't see how the linked commit does change the load order. I'm pretty sure that it's because of my rewrite:

https://github.com/wikimedia/pywikibot-core/commit/41c7eb19fd3fb6f4c3ade896b5fb37ab21e1958d#diff-1

Before it also checked cwd:

https://github.com/wikimedia/pywikibot-core/blob/0d6a3d724a2bf7068ec0e4baa3bab2bb65648bf0/pywikibot/config2.py

It's not about the cwd, but about the directory-pwb.py-is-in!

-if "PYWIKIBOT2_DIR" not in os.environ:

• os.environ["PYWIKIBOT2_DIR"] = os.path.split(file)[0]

^ that explicitly set PYWIKIBOT2_DIR to the pwb.py dir if it was not set before.

Probably a dup of bug 72680

Now the logic is in config2.py.
os.path.split(file)[0] => /home/user/python/core/pywikibot

How it it supposed to know where pwb.py is?
Is it safe enough to assume assume ../pywikibot?

Indeed duplicate.

We can either pass the pwb.py location to config2.py somehow (environment variable, maybe some global variable? not sure), or just use '..', which should be fine in most cases. Maybe we should check whether there actually is a pwb.py in that directory to be sure we're not installed.
