The function `get_system_username()` silently returns an empty string when
exceptions occur (ImportError, KeyError, OSError).

This may make debugging difficult and can lead to unexpected downstream
behavior where an empty username is treated as valid.

### Expected behavior

It might be helpful to at least log this situation (e.g., at debug level)
to improve visibility.

### Context

This behavior occurs in environments where `getpass.getuser()` fails
(e.g., restricted systems or missing passwd entries).

Hi, I have submitted a PR to address this issue.

GitHub PR: https://github.com/django/django/pull/20982

This adds debug logging when get_system_username() fails, improving
visibility without changing behavior.

Feedback is welcome. Thanks!

Comment:

We are talking about management command used rarely by users. I see no
value is raising an exception or adding a logger here. This is not
something that will not be noticed when executing a command.
