Feature: Installer to create LUKS encrypted Live USB
In order to protect the integrity of the Tails OS from someone who gets physical access to the USB stick it would be amazing if the whole USB stick (except boot partition) would be LUKS protected - including the whole OS. This makes it way harder to modify the OS in a way to get access to keys, data, etc... E.g. https://lumit.it/how-to-get-a-tails-luks-master-key/
I am using MX-Linux for a while on an encrypted USB stick as Live System and the installer allows to encrypt the whole USB stick with LUKS encryption. See Encrypt option https://mxlinux.org/wiki/help-files/help-mx-live-usb-maker/
Something similar would be amazing!
