I thought it'd be a nice idea to combine any and all distribution media for a release into a single medium--a USB drive, of course. I'd start by creating my USB drive by extracting the first DVD to it, thereby ensuring the boot block and boot material is where it should be. But then what do I do with the additional media? Surely there will be some files with the same name among the individual pieces of media, and some will probably contain the same info while others probably will not. What do I have to watch for and make sure I don't overwrite, but add to, when extracting files from the additional disks to bag it all up and make a single medium which contains everything in one place?
