We're looking to have an option added to the liveusb-creator to select
an option "Use entire stick for image" (or something similar) which
would then get rid of the sqashfs all together and install the ext3
partition straight to the usb stick so there's no issues with corrupt
overlays and other related issues as it will be a plain filesystem
straight onto a usb stick so there'll be no weird fu in between.

Cheers,
Peter
