Switching the Kernel

I'm sure there are maaany ways to switch out the ubuntu kernel, here is what I do. Going from 4.4 to 4.10 as an example.

1. Download the kernel version that you're after

wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.10/linux-headers-4.10.0-041000_4.10.0-041000.201702191831_all.deb
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.10/linux-headers-4.10.0-041000-generic_4.10.0-041000.201702191831_amd64.deb

#!/bin/sh

mountandwrite() {
        i=$1
        echo "mounting $i"
        mount -t overlay -o lowerdir=./lower,upperdir=./upper$i,workdir=./work$i overlay target$i

        echo "writing $i"
        dd if=/dev/urandom of=target$i/foo bs=10M count=10
}
