Persistence Across Bootburn Flashing Using Persistent Partition

NVIDIA DRIVE^? OS provides persistence across bootburn flashing for user data and metadata partitions. The persistence works by reserving a partition in bootburn that is not written or modified in the flashing process. Due to this effect, the data in this partition is completely unchanged across bootburn flashing. After the filesystem is loaded, the user data partition is mounted on /home, and the persistent metadata is overlayed on /etc.
