<p>On GRUB, you can edit the kernel command line parameters, which will be parsed
as variables on the init system. Not all of the parameters will be acted upon,
but all of them will be set as variables on the init script. For example an
example command line, and how it is interpreted.
</p>
<div class="example">
<pre class="example">BOOT_IMAGE=/boot/vmlinuz root=/dev/sda2 rw loglevel=3 quiet
</pre></div>

<p>This command line will be parsed to set the following variables:
</p>
<div class="example">
<pre class="example">BOOT_IMAGE=/boot/vmlinuz
root=/dev/sda2
rw=1
loglevel=3
quiet=1
</pre></div>

<p>Some of these variables, such as &lsquo;<samp>rw=/=ro</samp>&rsquo;, &lsquo;<samp>loglevel</samp>&rsquo;, and &lsquo;<samp>quiet</samp>&rsquo;, will be
used by the init system to change the behaviour of the startup.
</p>
