Use bind mount for /tmp/.X11-unix for better compatibility.

Is your feature request related to a problem? Please describe.
Some programs (Eg. snaps, flatpaks) need to remount it in the chroot environment. But symbolic link can't be remounted.

Describe the solution you'd like
Make it a bind mount instead of a symbolic link.

Describe alternatives you've considered
None.

Good suggestion, I've made this change and it will be available in the future version of WSL.

Has this fix been released? Encountered this issue with WSL and Steam today.

WSL version: 2.1.5.0
Kernel version: 5.15.146.1-2
WSLg version: 1.0.60

Error:

bwrap: Can't mount tmpfs on /newroot/tmp/.X11-unix: No such file or directory

Workaround (no idea if this is the correct way to do it):

sudo rm /tmp/.X11-unix
mkdir /tmp/.X11-unix
sudo mount --bind /mnt/wslg/.X11-unix /tmp/.X11-unix
