How do create an encrypted system with multiple Linux distributions?

http://askubuntu.com – A few weeks ago I created a completely encrypted system on a notebook and must say I like the idea. It's a little bit annoying to enter the password on every boot, but it's nice to know even if I loose the computer I don't give my data to other people. With the alternate-cd it's easy to do. Now I have to setup a new system where I want to combine the new idea with my usual usage strategy. There I have more partitions: 3 system, Home, Different Data-Partitions for vm-data, photo-data and mp3-data. The background is that I prefer not to update a system. I prefer to install the new version para (HowTos)

I have a Debian Linux system (amd64) installed on a RAID-1 system encrypted device (LVM on LUKS) and will have a RAID-6 of >=4 disks where I'll put my data (LUKS and maybe LVM).

I think the basic idea is to unlock the system encrypted partition (at boot at local or via ssh) and to store a keyfile in /etc/crypttab for the RAID-6 encrypted partition. Does that pose a security risk ? I mean ...

I have been assured that this is possible, but have so far not found any reference that will clue me as to how to do it. I need to deploy an "appliance" with software and data that the user is permitted to use, but which I would prefer to keep them from poking around inside. The user will not have root access, so the running system should be protected.

I tried everything since days, so now i'm asking you.

I got an Ubuntu system on my old hdd, wich is connectet via usb to this system and a sdd is build in my notebook. At the moment i am running an Ubuntu system from an usb stick.

I have tried to clone my disk(change uiid, etc), to transport the data via deja dup and much more. The result was nothing or strange things.

Cryptkeeper is a Linux system tray applet that manages EncFS encrypted folders. It is a handy tool for saving your private data into an encrypted folder, the folder default is hidden and need password to unencrypt using Cryptkeeper applet. Note: I would recommend TrueCrypt if you’re planning to encrypt larger collections of data that you want really secure.

From what I understand after reading this article in the wiki LVM is an underlying layer below the partitions that you usually work with. Basically a structure on the HDD on top of which you have your partitions and file systems.Now, before asking my – hopefully not embarrassingly stupid – question, I should probably describe my situation:I have two HDDs here, one of which is currently in use.

I want to install Ubuntu 12.04 LTS x64 alongside with Windows 7.

On my Debian-Testing-System, I want to completely conceal the home folders. That means, I not only want the data to be encrypted, but I also want to preclude determining any (or most) information from the encrypted data.

For instance, also file names should be encrypted.
