        Create multi boot USB stick/hard disk with whole iso/s on vfat/fat32 partition
        keeping existing data untouched.

Note: File size greater than 4G is not usable on vfat/fat32 partition so the
        live CD/DVD iso file should not exceed this limit.

Note2: Install 32bit/x86 iso on the stick first if creating multiboot with both
        x86 and x86_64 arch images.

Note3: Requires: syslinux, fuseiso and dd_rescue/ddrescue installed on the system running this.

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-12.2-1-i686.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 Ubuntu      : live-fat-stick --ubuntu /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 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.

Please note that using isohybrid option will remove all existing data on the USB device
        and create new partitions.

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

openSUSE users can install it via 1-click from here:
        http://software.opensuse.org/package/live-fat-stick
