Hints for building and integrating a new kernel into the cryptobox:

1) get the source
download it from http://kernel.org (at least 2.6.11)

2) configure
- copy the current kernel config from the cryptobox/trunk/kernel
  directory to the kernel source directory as ".config" (the .config
  can also be found in the current kernel-image-cryptoboxX.Y.deb packagefile)
- make menuconfig
- make-kpkg --rootcmd fakeroot --revision=cryptoboxY.X kernel_image
  (replace "Y.X" by the current cryptobox release)

3) integrating
- copy the debian kernel package (see above) and the config file to cryptobox/trunk/kernel
- change the "unpackdebs" setting in cryptobox/trunk/etc-default.d/dfs-cbox.conf
- add the new kernel package and the config file to the repository (svn add)

4) afterwork
- run "cryptobox/trunk/scripts/cbox-build.sh dfsbuild" to create a fresh base system
  including the new kernel
- test the box with your new kernel
- enjoy it! :)
