The systemctl is now available in wsl
Add these lines to the /etc/wsl.conf
note you will need to run your editor with sudo privileges, e.g: sudo nano /etc/wsl.conf
[boot]
systemd=true
And close out of the nano editor using CTRL+O to save and CTRL+X to exit.
With the above steps done, close your WSL distro Windows and run wsl.exe --shutdown from PowerShell to restart your WSL instances. Upon launch you should have systemd running. You can check this with the command systemctl list-unit-files --type=service which should show your services’ status.
