[Grml] grml live-usb and truecrypt?

Dear list,

I've been using grml-live-usb sticks for disaster cases since a few years. No I have "my own" disaster case - the system SSD starts to break, and the datastore-hdd is true-encrypted. I most probably won't get a network connection during the recovery process.

How can I get truecrypt onto my usb-key "in advance"?

Thanks for any hints in advance, Stefan
