[Grml] grml live-usb and truecrypt?

[Stefan /*St0fF*/ Hübner]

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
