Un systemd sous debian via WSL : genie

curl -s https://packagecloud.io/install/repositories/arkane-systems/wsl-translinux/script.deb.sh | bash

Voici l'erreur avec un systemd natif :

systemctl enable --now mongod

System has not been booted with systemd as init system (PID 1). Can't operate.
Failed to connect to bus: Host is down
