I don't understand how it could corrupt the UNDERLYING vfat partition,
but that is what happend to me twice. I was unable to mount the USB
stick as a normal vfat data drive from a regular (non-Live) booted
system after filling and crashing the persistent overlay when it was
booted as a Live USB system. It seems there is a vfat bug that is
corrupting the filesystem.
