Because new images place the bootblock in a separate region from the primary CBFS, performing an update-fit operation requires reading an additional section and choosing a different destination for the write based on the image type. Since other actions are not affected by these requirements, the logic for the optional read and all writing is implemented in the cbfs_update_fit() function itself, rather than relying on the main() function for writing as the other actions do.
