add web browser text based on rescue from boot.iso

[Sergio Monteiro Basto]

Hi,
using boot.iso from releases/12/Fedora/x86_64/os/images/
I can do a usb boot disc and run the rescue mode, easily, with command 
livecd-iso-to-disk boot.iso /dev/sdc

And install.img is write on /images.  
I also could update install.img using method wrote in :
http://www.fedoraproject.org/wiki/Anaconda/Updates#How_to_Create_an_Anaconda...

but I don't know how or where
with /usr/lib/anaconda-runtime/buildinstall and/or pungi -B , can
customize my install.img.

For example I'd like add lynx (to install.img), how I can do that ?

Other question rescue mode don't have any web browser text based ?

Thanks in advance,
