title: How to change config files in openwrt?
body: <p>I have to add a <code>dns</code> entry in <code>/etc/config/network</code>, so I added it in
  <code>package/base-files/files/etc/config/network</code>. Then did</p>
  
  <pre><code>make V=99 package/base-files/clean
  make V=99 package/base-files/compile
  </code></pre>
  
  <p>Now it generates an <code>.ipk</code> at <code>bin/x86-eglibc/packages/base/base-files_156-unknown_x86.ipk</code>. If I install this by <code>opkg install base-files_156-unkonwn_x86.ipk</code> the change is not seen. What am I missing?</p>
