| bootloader writes a certain bit pattern to a previously agreed memory |
| location. If a userspace app decides that the kernel has booted ok and |
| that the user space environment is sane, it tells the kernel which then |
| flips a bit in DRAM to communicate to the bootloader that this image is |
| considered "good". Now, if the system reboots due to some failure |
| condition before said bit has been flipped, the bootloader is able to |
| detect this situation and switch back to a different kernel/rootfs |
| image. |
