Ubuntu 8.10 Persistent flash drive install using the Live CD. The tutorial will provide guidance to a user to install Ubuntu 8.10 Intrepid Ibex to a USB flash drive while booted from the Live CD. In addition the persistence or casper persistent feature will be utilized to automatically save changes back to the thumb drive as you work, and then restore those saved changes upon subsequent boots.
It is important to note that the tutorial will utilise a separate ext casper-rw partition instead of a loop file. The process enables the user to have a partition that is larger than the 4GB fat32 file size limit for saving and restoring changes.
