how to make magic/sysrq across reboot?
<p><code>sysctl kernel.sysrq=1</code> makes it work on arch.
but on reboot it goes back again.</p>

<p>i write 1 vlaue to the file <code>echo 1 &gt; /proc/sys/kernel/sysrq</code>
but that is temporary unfortunately.
i am looking for a permanent way.</p>

<p>is there a way, <em>and not just for this but any command after reboot</em>.
can i bind reisub to any shortcut key with the help of command line.</p>

<p>any suitable way will be and should be thought out.</p>

<p>how does it all work inside the kernel.
in ubuntu it is enabled by default, how did they manage to enable it?</p>
