I followed the instructions at the following web site to install a bootable copy on knoppix 5.02 to a USB Thumb drive and create a persistant area on the same Thumb drive. If I choose to use the persistant information at boot time, I assume the mounted IMG is actively writing to the USB flash, correct? Is there an option to write the persistant imformation from the USB drive to the RAM drive at boot up then save to USB drive on shutdown.? With this option the IMG file containing the persistant information would only be updated once per session thereby minimizing writes to the flash. Comments/Ideas???
