A few people have attempted to use the systemd documentation to create a reimplementation. Bearing in mind that the task is complex and largely thankless, all the folks making attempts that I&#x27;ve heard about have reported that the available documentation does not provide enough information to complete such a task.<p>Note: I KNOW that documentation is <i>seriously</i> hard. But, one of the rebuttals of the &quot;Systemd is complex and monolithic&quot; assertion is &quot;Systemd is fully documented, so you can replace <i>any</i> part of it with one that you&#x27;ve authored.&quot;. You can&#x27;t <i>honestly</i> make that rebuttal if the state of your documentation doesn&#x27;t support your claim.
