What would be needed? I mean, obviously, the captive drivers would need to be available and loaded when the system boots, and some editing to knoppix-autoconfig would be in order so that NTFS drivers are checked for a persistent home image.

Or maybe you could just boot normally, then activate captive, mount the drive, rsync the image to your home, and then restartx...?

Anyone have ideas for this? I'd like to work out a way to run persistent home on NTFS.
