Raspberry Pi: Full disk encryption

[cypher]

Hi,

I'm trying to set up an arch linux with full disk encryption on my RPi. I created two partitions with vfat and ext4, (the latter one is located in a LUKS encrypted partition) and copied the files from the Arch RPi Image into.

Now I'm not quite sure how to proceed. My long term goal is unlocking the system via ssh (using the initramfs) but as a first step unlocking by entering the password via keyboard should be ok. For the latter case (the unlocking via keyboard), do I have to recompile the kernel to load the appropriate modules? And what changes do I have to apply to the cmdline.txt?

By the way, is there already an initramfs build into the Arch RPi kernel?

Best,
cypher

THere was a thread in the raspberrypi section about exactly the same thing you are trying to do, with success. If I remember correctly ssh was built into initrd. Take a search.

Thank you! I already did a quick search and found nothing. Same thing after your post. In the end i found it by looking over all the topics in the RPi-section . Strange.

However, for everybody else looking for ful disk encryption on the RPi, this is the link:

Here's the link to the Tutorial based on the discusion: https://gist.github.com/pezz/5310082

A big thank you for pezz tutorial and for you pointing me at it !
