1.1: Kernel
To actually get an executable kernel,
You either grab BOOT_IMAGE from /proc/cmdline, or
compile the kernel

If you wish for a quick grab:
Then you must:
cat /proc/cmdline
And grab whatever file the $BOOT_IMAGE flag is.
, Or if you wish to compile:
mkdir ~/lfz
cd ~/lfz
git clone --depth 1 https://github.com/torvalds/linux
cd linux
make menuconfig
make -j$(nproc)

Once you have the kernel if you've compiled, The makefile will tell you where it put the bzImage,
just grab it from there and copy it
to your work folder ~/lfz
