File INSTRUCTIONS.fat.txt of Package live-fat-stick

If --isohybrid option is used then it removes all existing data and creates
new partitions.

Run this command as root (su -, not sudo)
    live-fat-stick isopath stickpartition
e.g.: 
    live-fat-stick /home/geeko/openSUSE-Edu-li-f-e-42.2-1-x86_64.iso /dev/sdXY

To add various distribution iso to the stick, run the following:
    For openSUSE: live-fat-stick --suse /path/to/openSUSE-filename.iso /dev/sdXY
    For openSUSE with persistence    : live-fat-stick --suse-persistent /path/to/openSUSE-filename.iso /dev/sdXY
    For Ubuntu clones     : live-fat-stick --ubuntu /path/to/ubuntu-filename.iso /dev/sdXY
    For Ubuntu clones with persistence      : live-fat-stick --ubuntu-persistent /path/to/ubuntu-filename.iso /dev/sdXY
    For Mint: live-fat-stick --mint /path/to/mint-filename.iso /dev/sdXY
    For Fedora: live-fat-stick --fedora /path/to/fedora-filename.iso /dev/sdXY
    For iPXE: live-fat-stick --ipxe /path/to/ipxe.iso /dev/sdXY
    For isohybrid: live-fat-stick --isohybrid /path/to/isohybridimage.iso /dev/sdX

isopath should be full absolute path of iso image and the device should be 
actual partition on the stick like /dev/sdb1, /dev/sdc1,/dev/sdc2...

The stick partition has to be vfat/fat32 format if the image is not isohybrid.

Persistent option requires minimum 500M free space on the USB device apart from
the spare needed by iso image. To allocate more space for cow file use cowfile
variable like this example: "export cowsize=1000M" before running the script

Please note that using isohybrid option will remove all existing data on the
USB device and create new partitions. Also note that /dev/sdX is used

Run live-fat-stick -l(or --list) to list the possible usb storage devices available.

It is possible to boot multiple distributions and iso images from same device, 
should work with all recent openSUSE or Ubuntu live iso images. Fedora iso is
not copied but is extracted as it does not support booting from iso.
This tool creates multi-boot capable USB stick/hard disk images with
whole ISOs on a FAT32 partition, keeping existing data untouched.
