I would describe it differently: - firmware finds bootloader "somewhere" on some ESP, bootloader finds boot.cfg in the same directory (if it exists) - otherwise bootloader guesses a partition from where the kernel is loaded and also checks for a boot.cfg in the root directory of that partition. The bootme flag may be involved in this step (but is not required). - kernel gets passed the location where it was loaded from and optional other arguments if boot.cfg was found. kernel decides what to use as root partition. A /boot.cfg on this partition is not needed nor usefull unless it happens to be the same partition as where the kernel is loaded from (the item before) and there was none in the ESP directory (the first item).
