Hi, I don't have Bluetooth, I don't need RPC, etc., yet the kernel initialized all those processes I have never defined and I don't need. Where those things defined to let the kernel to initialize them in boot process?
It is a small resource device, how can I get rid of those things I don't need? As I said, in older version of image, I have never seen those things, where are coming from? Thank you.
