@ze You would have to do the partition backup before flying in anticipation of being searched at the airport. In which case, detaching/encrypting header is more robust.

It's not without problems though.

Doing so effectively creates a dracut/initramfs fork of the QubesOS installer. Kernel updating seems to be a common issue, as is the sleep function. Both require regular attention to grub kernel parameters, a PITA.

Still, I will try it out at some point and see what the tradeoff is.
