Bit later then planned.

The "init" file is the initramfs init-file.
The "config" is what I configure in the kernel:

$ zcat /proc/config.gz | grep initramfs
CONFIG_INITRAMFS_SOURCE="/usr/src/initramfs/config"

There are a few changes you'll need to do:
1) In the "init" file, change the name of the swap-partition you use
2) In the "config" file, change the following paths:
  - init-file
3) In the "config" file, run the command mentioned at the end of the file and
    add the result of the command to the end of the " config " file.

I have been using this config succesfully for over a year on my laptop.
