Yes, doing rebuild is one of the direction in wice we are moving,
but a simple persistent customization of the main release via
persistence has different purposes.

Like a sport car to have fun, fast but that need a lot of care, respect
a 20 years old lifeboat, found JIT when the ship sunk.

Glad to know this. Hope to have a finished work soon.

Yes, we of course already considered this issue.

Worst, we plan to give preinstalled persistent USB keys with a
predefined password for persistence equal for all copies.

We'll give instruction to change it immediately (and how to do this)
and to reinitialize the encrypted partition (why and how to do this)

But target are totally non technical users that normally goes abroad
in Internet Cafe' and use Gmail .... a weak solution is far, far better
than current situation, and has a simple and straightforward path for
hardening.

But I'm aware that this is an highly controversial issue.

Thanks for you help, understanding & support.

BTW, are Tails-related event planned during OHM2013?

Thanks. Marco
