[$] Fedora and optical media testing

Once upon a time, Linux was installed from a stack of floppydisks-thankfully cassette tape "drives" were long in the past at thatpoint-but floppies were superseded by optical media, first CDs and thenDVDs. These days, those options are starting to fade away in most newcomputer systems; just as it is now rather hard to find a floppy-based Linuxinstaller, not to mention the media and drives themselves, someday opticalmedia installation will disappear as well. For Fedora, that day has not trulyarrived, though a somewhat confusingly presented proposal on the Fedoradevel mailing list is, to a limited extent, a step in that direction.
