Installing with a root cryptofs in eeebuntu

I have an Asus 1000HE eeepc. I like it, mostly its battery life. I installed eeebuntu not being a big windows fan and was displeased when I discovered that you could not directly install to a root cryptofs. I did it anyway, although it takes a round-a-bout method to accomplish.
For those that do not know, cryptofs is a whole disk encryption solution in linux. It is transparent to the user, aside from having to enter a passphrase (which can be very long) when you mount the disk. Making / (root) cryptofs requires some modification to the initrd so that it will load the appropriate modules, set up the proper pseudodevice entries, and then mount the disk. Swap can also be made encrypted making it even more difficult for anyone to get anything out of your system should it fall into the wrong hands.
Unlike some of the other tutorials out there I do not require you to do an intermediate temporary install, this means that your entire disk except /boot can be encrypted in one go. (continue reading…)
