I use following fstab to get access to WSL 1:

//wsl$/debian /wsl/debian      ntfs binary,posix=0,user,noacl,notexec 0 0
//wsl$/ubuntu /wsl/ubuntu      ntfs binary,posix=0,user,noacl,notexec 0 0
//wsl$/alpine /wsl/alpine      ntfs binary,posix=0,user,noacl,notexec 0 0

There are problems to access some files (their attributes) but they are
special like /dev...

I have never tried WSL 2. I believe it uses P9 network fs.

Probably you have to use full distro names as reported by:

  wslconfig.exe /list

not just '//wsl$'.

See following:

https://devblogs.microsoft.com/commandline/whats-new-for-wsl-in-windows-10-version-1903/
  Announce of P9 server for WSL compatible with UNC.

Cygwin works with UNC according to the doc, that's why I tried it with fstab.
