So if I want to encrypt my whole HDD with e.g.: LUKS (are there any better solutions? - e.g.: in performance?) then I have to download&burn a "ubuntu-11.04-alternate-amd64.iso" CD. That's ok, I understand.
The Question: Are there any minimal ISO's (like the Debian netinstall CD) *WITH LUKS support?
So that I just have to download an ISO that weights a couple of MByte's and install it using LUKS so that I could have a fully encrypted HDD?
