&gt; 1. Yes. 2. Yes. ... 3. No...<p>Good. Far too many people in these conversations have poorly-informed opinions.<p>&gt; Folks who aren&#x27;t running &#x27;RedHat&#x27; (sic) use systemd, sysvinit, or ... upstart [sic] ...<p>These are init and RC systems, not services. :)<p>&gt; ...or pretend to use upstart but as a thin wrapper to sysvinit.<p>I dunno. The Upstart project page says:<p>&quot;Upstart is an event-based replacement for the &#x2F;sbin&#x2F;init daemon which handles starting of tasks and services during boot, stopping them during shutdown and supervising them while the system is running.<p>It was originally developed for the Ubuntu distribution, but is intended to be suitable for deployment in all Linux distributions as a replacement for the venerable System-V init.&quot;<p>If I look at the file list for the upstart package, [1] I see that upstart provides its own &#x2F;sbin&#x2F;init, &#x2F;sbin&#x2F;halt, and -it seems- just about everything that&#x27;s provided by the sys-apps&#x2F;sysvinit package on my Gentoo system.<p>Also, sysvinit and sysvrc <i>aren&#x27;t</i> the same thing. OpenRC -the default Gentoo RC system- is a <i>sysvrc</i> replacement. [2] It relies on sysvinit (or similar) to get its work done, and is an <i>obvious</i> improvement over sysvrc.<p>If you <i>were</i> aware of the distinction, and have the time, would you be so kind as to mention the top N worst things about <i>sysvinit</i>? If you weren&#x27;t aware, and have the time, would you care to learn the distinction, and then bounce on back and answer the query?<p>Thanks in advance. :)<p>[0] <a href="http:&#x2F;&#x2F;upstart.ubuntu.com&#x2F;" rel="nofollow">http:&#x2F;&#x2F;upstart.ubuntu.com&#x2F;</a><p>[1] <a href="https:&#x2F;&#x2F;packages.debian.org&#x2F;jessie&#x2F;amd64&#x2F;upstart&#x2F;filelist" rel="nofollow">https:&#x2F;&#x2F;packages.debian.org&#x2F;jessie&#x2F;amd64&#x2F;upstart&#x2F;filelist</a><p>[2] If I&#x27;m reading this right, Debian even maintains a sysvrc package: <a href="https:&#x2F;&#x2F;packages.debian.org&#x2F;jessie&#x2F;sysv-rc" rel="nofollow">https:&#x2F;&#x2F;packages.debian.org&#x2F;jessie&#x2F;sysv-rc</a>
