on WSL2 in Ubuntu I have inside a folder: ‘wsl$’. Ubuntu says it’s not a symlink – but a directory!

I created ‘wsl$’ by trying to connect PHPStorm (installed on Windows) with a docker container in WSL.

I worry that if I rm -r the directory, the system either will collapse – or since it’s turtles all the way down: the universe will eat itself :-).

How can I “safely” delete it?
