Another question which crops up every now and again: "why is my kernel so
big?". People must be using "config -g" without knowing it or something... PR: 19997 Submitted by: Eric Ogren <eogren@earthlink.net>

<answer>
|
||||||
|
<para>Chances are, you compiled your kernel in
|
||||||
|
<emphasis>debug mode</emphasis>. Kernels built in debug
|
||||||
|
mode contain many symbols that are used for debugging, thus
|
||||||
|
greatly increasing the size of the kernel. Note that if you
|
||||||
|
running a FreeBSD 3.0 or later system, there will be little
|
||||||
|
or no performance decrease from running a debug kernel,
|
||||||
|
and it is useful to keep one around in case of a system
|
||||||
|
panic.</para>
|
||||||
|
|
||||||
|
<para>However, if you are running low on disk space, or
|
||||||
|
you simply don't want to run a debug kernel, make sure
|
||||||
|
that both of the following are true:</para>
|
||||||
|
|
||||||
|
<itemizedlist>
|
||||||
|
<listitem>
|
||||||
|
<para>You do not have a line in your kernel
|
||||||
|
configuration file that reads:</para>
|
||||||
|
|
||||||
|
<programlisting>makeoptions DEBUG=-g</programlisting>
|
||||||
|
</listitem>

<listitem>

|
||||||
|
</listitem>
|
||||||
|
</itemizedlist>
|
||||||
|
|
||||||
|
<para>Both of the above situations will cause your kernel to
|
||||||
|
be built in debug mode. As long as you make sure you follow
|
||||||
|
the steps above, you can build your kernel normally, and you
|
||||||
|
should notice a fairly large size decrease; most kernels
|
||||||
|
tend to be around 1.5MB to 2MB.</para>
