Rootfs Reduction

Jetson Xavier NX has a built-in eMMC of about 16GB.

However, after installing the pre-built system image plus NVIDIA SDK Components, there will be only 400MB left.

eLinux has a great document to describe how to reduce unnecessary files.

For example, the following command can release around 1.5GB of storage.

sudo apt clean    # clean debs in /var/cache/apt/archives

You may refer to eLinux's full document herearrow-up-right to remove unnecessary example code.
