#Prereqs
sudo apt-get install build-essential libncurses5-dev

#Make Kernel / Modules:
sudo mkdir /data/kernel
sudo cp -R linux-4.1.21-x86_64/ /data/kernel/
sudo ln -s /data/kernel/linux-4.1.21-x86_64 /usr/src/linux

export KERN_DIR=/usr/src/linux
cd /usr/src/linux
#sudo cp .config .config-old
#Normal kernel build would be
#sudo cp arch/x86/configs/defconfig.x86 .config
#ReadyNAS build - ensure this file exists and you use it instead, using the default configs will get you an "invalid module format" error
sudo cp arch/x86/configs/readynas_defconfig .config
#Check and potentially move module dirs in
#ls /lib/modules
#Remove old - won't work if any modules are loaded
#sudo rm -Rf /lib/modules/
sudo make clean mrproper
sudo make ARCH=x86_64
sudo make modules_install ARCH=x86_64

#You should now be able to do a:
sudo modprobe configs
sudo cat /proc/config.gz | gunzip
#And get a list of the current kernel config

Line 46 should come directly after line 51, since line 51 clears out the .config file that exists in the folder.
