It's what WSL Debian creates when I 'ln -s' inside its own filesystem.

Windows' own "dir" command shows it as

22.03.2021  22:34    <JUNCTION>     link_to_a [...]

But it cannot do anything else with it.  Even fsutil doesn't work on 
that thing:

C:\prg\test>fsutil reparsePoint query \\wsl$\Debian\home\hbbro
Fehler:  Unzulässige Funktion.
