Creating a bootable USB from an iso

Convert .iso to USB installation
With the guide from [1] you can install the .iso contents non-destructively onto a USB partition. Leave out all the partitioning or formating stuff to prepare an existing and used USB drive for DSL booting:
Note: All path names are examples! Please adapt or you may corrupt existing partitions or files.
- Mount USB drive, with e.g. mount /dev/sdx1 /flash – can be either FAT16 or FAT32!
- Mount ISO image, with e.g. mount /tmp/dsl-3.2.iso /tmp/iso -o loop
- Copy all contents from ISO to USB drive: cp -vr /tmp/iso/* /flash/
- Rename and move syslinux files to root directory: mv /flash/boot/isolinux/* /flash/
- Rename isolinux.cfg: mv /flash/isolinux.cfg /flash/syslinux.cfg
- Unmount USB drive: umount /flash
- Install syslinux: syslinux /dev/sdx1 and eventually set the MBR boot flag for this partition (with fdisk).
