Read it through but hard to grasp all the details. One thing I&#x27;m sure is that for non-systemd &quot;legacy&quot; init systems I know what I&#x27;m doing, for systemd I most of the time don&#x27;t know what&#x27;s going on there, it&#x27;s still like a blind art after using it for a while, overly abstracted might be one reason for that.
