Ubuntu, Truecrypt and hidden volumes
I was wondering if anyone knows a way to create a hidden volume, giving me "plausible deniability" whenever I'm forced, let say, at some paranoiac border (e.g. USA, Canada, China), to reveal the my pass phrase, like Truecrypt is able to do on a Windows based system?
It doesn't necessarily have to be TrueCrypt, but any other method or software ending in me having a Linux based system running with a hidden volume is wanted.
Just to be sure that my question is correctly interpreted. I would like to have 2 different pass phrases. The first is for opening a "work" system that holds data that doesn't need protection. The other is for opening a "hidden" system that holds data that DOES need protection.
