This is a guide about getting a Linux distribution up and running on your Nexus 9. The goal of this thread is to give a basic understanding about how to get a basic system running, but not working throughout all the kinks that come with doing so on tablet style hardware.
This guide will be non-destructive, and won't touch the data on your tablet. Unless of course you've yet to unlock your bootloader, which if that is the case then shame on you.
Some prerequisites before starting this project with your Nexus 9
First we are going to be building an initramfs. This is a small filesystem with a bare minimum set of tools that can be loaded in to RAM space and use. We will be using this while we are initially getting our kernel up and running, to make sure we didn't mess anything up.
Next we will move on to building the actual kernel for the device. We will be running a Android kernel since Nvidia hasn't been the quickest on their attempt to upstreaming everything required to run this device on a upstream Linux kernel. So we'll be running a 3.10 kernel, which is a heck of a lot better than some 3.0 or 3.4 thing that older devices are on.
Third we will be building our rootfs that will run from an external USB storage device, so we don't affect any data actually on the tablet. I may also add to the guide how to partition your internal storage space so we can use that instead.
[Step 0/4]
We need to set up our build environment on our host Linux distribution before we begin anything. I'm going to assume that the host Linux system we are running is Debian/Ubuntu based, so we'll be using apt to grab our packages we need.
This installs the host gcc and AArch64 cross compiler, along with git. We will need these tools to build everything required.
Things that don't work.

sudo apt-get install gcc g++ git gcc-4.9-aarch64-linux-gnu g++-4.9-aarch64-linux-gnuThings that don't work.
- Rebooting
- Touchscreen
- Way more things that people care about
