Reset WSL2 Quickly

If you're getting Network Unreachable in WSL2 for some reason, try this:

sudo Disable-WindowsOptionalFeature -Online -FeatureName -NoRestart `
    $("VirtualMachinePlatform", "Microsoft-Windows-Subsystem-Linux")
sudo Enable-WindowsOptionalFeature -Online -FeatureName `
    $("VirtualMachinePlatform", "Microsoft-Windows-Subsystem-Linux")

Systemd in WSL2

It should 'just work' now, but sometimes you may need to set something in your wsl.conf:

# /etc/wsl.conf
[boot]
systemd=true
