You can do that, yes. The only other possibility is outright replacing the package providing the file (since you are free to specify whatever packages you want in the image, though you may have to break up packagegroup-core-boot to do it). This only works of course if either there are no dependencies on the package or you can satisfy any dependencies that might exist. It could be that for your "flash OS" image there aren't any, but it depends what it has in it. It may be simpler just to hack it after the fact though. Note that you don't have to add an IMAGE_FEATURES item to do that - you could simply create a shell/python function and add a call to it in ROOTFS_POSTPROCESS_COMMAND. If the changes to the files are substantial you could even supply the alternative files in a separate package and then move them over the top of the original ones in the postprocessing function to save jumping through hoops adding files to the image recipe.
