`debootstrap` Parallel Download Patch

Distro	debootstrap version

This is a guide to build a Linux 6.12 for Nvidia Jetson AGX Orin Developer Kit 32GB with Jetpack 6.2 (r36.4.3) and flash it on external storage.
Currently, Jetpack 6.2 does not support Linux 6.12, and the patch below still contains a lot of bugs. Use this document for experiments only.
Since display output is not supported, use the debugging serial port until SSH connection is established. This requires two cable connections between the host and the target device: one for data connection and one for debugging serial connection. For details on using the serial port, refer to here.
