We normally know that WSL2 normally do not have systemd it generally starts on init daemon! But recently from year 2022 we can also use systemd by enabling the sysboot to systemd in wsl.config.So I did that and after starting dbus service and rebooting systemd was enabled! But when I now run top command I see both init and systemd ! So I am having conufsions because I was taught pid 1 is the startup process and it can be either systemd or init! how both are existing I don't understand! Can anyone clarify me?
