# I'm using non-generic busybox binary which is specifically build for arm64, because I need fstrim and some other commands.
# I also enabled init.d support by editing /system/etc/init.qcom.post_boot.sh, adding this (below) command to the last line of the file (init.qcom.post_boot.sh) to enable init.d:
#
# busybox run-parts /system/etc/init.d
#
# So, to fully install busybox into the system, I run this install command (after mounting /system partition to rw: mount -o remount,rw /system) via ADB:
#
# /system/xbin/busybox --install /system/xbin
#
# This is my personal tweaks for every ROM/Kernel made for Xiaomi Redmi Note 3 Pro (kenzo), I prefer my phone to run fast but also still maintaining better battery life.
