2.2.7. Live USB Persistence

Support for persistent changes with a Fedora Live image exists for Fedora 9 and later. The primary use case is booting from a Fedora Live image on a USB flash drive and storing changes to that same device. To do this, download the Fedora Live image and then run the following command:
livecd-iso-to-disk --overlay-size-mb 512 /path/to/live.iso /dev/sdb1
Replace /dev/sdb1 with the partition where you want to put the image.
Replace 512 with the desired size in megabytes of the persistent data, or overlay. The livecd-iso-to-disk shell script is stored in the LiveOS directory at the top level of the CD image. The USB media must have sufficient free space for the Fedora Live image, plus the overlay, plus any other data to be stored on the media.
