Hi,

I am trying to create a custom image with a modified config.xml (both in 
  /cf/conf and /conf.default). Reason: after reset of config I want to 
be able to reach the box over network, so I am setting correct 
interfaces and lan IP in the config.

For modification on the original generic-pc images I use the workon.sh 
script available at http://chrisbuechler.com/m0n0wall/downloads/.

Most things seem to work, the image boots and I can modifiy all 
parameters through web-gui.
Unfortunately I cannot modifiy the lan IP via the console menu. When 
trying I get the following error:


Fatal error: cannot unset string offsets in /etc/rc.initial.setlanip on 
line 85

I am trying to maintain all file permissions and have compared the ones 
of the original image and my custom: seems ok.

Am I missing something?
