1. Follow the instructions at http://gumstix.org/basic-cross-compilation.html to make uImage and kernel modules.  Use the attached defconfig file instead of the one mentioned in the instructions.
2. Download x-loader and u-boot from http://feeds.sakoman.com/feeds/gnome-r13/images/ 
3. Follow the instructions at http://gobysoft.com/wiki/InstallOnGumstixOvero to build the root filesystem.  Use the attached emdebian.conf file.
   1. If you've prepared the rootfs before then all you need to change for a new kayak is the hostname in /etc/hostname and /etc/hosts as well as the ip configuration settings.  
4. Use the instructions at http://gumstix.org/create-a-bootable-microsd-card.html to prepare the SD card and copy the MLO and u-boot.  The kernel image we built can be found in linux/arch/arm/boot.  
5. Copy the rootfs, sync, install kernel modules, and sync again.  Finally unmount the sd card.  

cd ~/gumstix/rootfs
sudo rsync -aP . /media/rootfs/
sync
cd ~/gumstix/linux
sudo INSTALL_MOD_PATH=/media/rootfs make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- modules_install
sync
sudo umount /media/boot
sudo umount /media/rootfs

Return to the goby wiki and follow the instructions to setup distcc on the gumstix.  Next install software according to the instructions on the software installation page.
