A small but useful feature for the CD ISOs of Fedora, openSUSE, MeeGo, and many other Linux distributions is that they are spun as hybrid ISOs. Hybrid ISOs allow the same CD ISO to be copied directly to a USB storage device (i.e. flash drive) without needing to rely upon any external utilities. Ubuntu ISOs have not supported this feature, but they do have their easy-to-use start-up disk creator to take care of this task. However, the daily ISOs for the Ubuntu Oneiric development cycle and all official Ubuntu CD releases going forward for i386 and x86_64 platforms will be now spun as hybrid ISOs.
