<p class="MsoNormal">> **1. systemd-bootchart stops too early**<o:p></o:p></p>
<p class="MsoNormal">> <o:p></o:p></p>
<p class="MsoNormal">> According to "man systemd-bootchart", the recommended way to invoke bootchart is via a kernel parameter:<o:p></o:p></p>
<p class="MsoNormal">> <o:p></o:p></p>
<p class="MsoNormal">> init=/usr/lib/systemd/systemd-bootchart<o:p></o:p></p>
<p class="MsoNormal">> <o:p></o:p></p>
<p class="MsoNormal">> That parameter causes systemd-bootchart to be executed as the new init process when we switch into the real root filesystem.<o:p></o:p></p>
<p class="MsoNormal">> <o:p></o:p></p>
<p class="MsoNormal">> bootchart does run, but it stops too early.<o:p></o:p></p>
<p class="MsoNormal">> <o:p></o:p></p>
<p class="MsoNormal">> In /etc/systemd/bootchart.conf, I have bootchart configured to collect 1800 samples at a frequency of 10 samples per sec. It should run for about 3 minutes.<o:p></o:p></p>
<p class="MsoNormal">> <o:p></o:p></p>
<p class="MsoNormal">> When I login, the svg file is already present under /run/log (but the system has only been up for about 10 secs).<o:p></o:p></p>
<p class="MsoNormal">> <o:p></o:p></p>
<p class="MsoNormal">> Doing "grep bootchart /proc/*/cmdline" when I login shows that bootchart is not running.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I opened <a href="https://github.com/systemd/systemd-bootchart/issues/58">
https://github.com/systemd/systemd-bootchart/issues/58</a> to track this.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The issue is worse than systemd-bootchart stopping too early. The genenerated svg is actually a zero byte file.<o:p></o:p></p>
