Bug#767195: Encrypted persistence not possible at boot time

[Rajko Albrecht <ral@alwins-world.de>]

Ok, I tried a lot, but with current live-build without patching
live-update-initramfs it is not possible getting a live system which
supports encrypted partitions at boot time for persistence.

So it must get fixed in live build tools, eg in live-update-initramfs.

Or cryptsetup changes the default - disabling security as default is a
somewhat strange idea.

I'd replaced the call to original update-initramfs with this line

CRYPTSETUP=y /usr/sbin/update-initramfs.orig.initramfs-tools "${@}"


(line 89 only)

Yes, of course, it must be configure-able.
