&gt; At last count SystemD has over 40 &quot;Interfaces&quot;. These are not publicly versioned standards. So there is no stable interface to even implement and there is no commitment that these &quot;interfaces&quot; will not change at any point in time.<p>Have you truly made no effort to research what you&#x27;re talking about? The most cursory of Googling would have dropped you at the Interface Stability Promise, saved you the time to post your completely worthless message, and saved me and others the time spent reading it.
