Emergency password for self destruction of LUKS keys

I would like to propose a ‘self destruct password’.

As suggested in Warnings session about persistence (https://tails.boum.org/doc/first_steps/persistence/warnings/index.en.html), `you can be forced or tricked to give out its passphrase`.

One solution for extreme cases could be a user defined password that would delete/corrupt with random bytes the persistent volume instead of opening It.

This discussion is check the viability of this feature.
