Move Ubuntu Path

You can move your Ubuntu distro to elsewhere as following. The drawback is it will be login root user by default. It's lost the integrity, consistency and other features. If you are aware about the risk then now worries else leave it as usual. It's recommended don't make changes or any engineering over there. Leave it as it's. Following example for experimental purpose nothing else. 

New-Item D:\var\wsl\ubuntu -Type Directory -Force
Set-Location -Path D:\var\wsl\ubuntu
wsl --export ubuntu ubuntu.tar

wsl --shutdown
wsl --unregister ubuntu
wsl --import ubuntu D:\var\wsl\ubuntu ubuntu.tar --version 2
Get-ChildItem

wsl -l -v
net stop com.docker.service
net start com.docker.service
