JetPack 4.6.4/L4T 32.7.4 occupies more space than its predecessors

Yes, and I remember that you just asked about this question:

External boot drive cannot be updated

I updated the system with latest jetpack for TX2 last night and found that the external drive cannot be updated or upgraded even it is a boot/root drive. The update procedure flashed the eMMC all over again. All my installed programs were gone. As a result, the eMMC became the boot drive again. Is this happened to all Jetson products? How do I update the system without using sdkmanager?

Have you managed to get it done?
