included scripts to bootstrap a root file system and create a disk image.
Those scripts have evolved into the [brickstrap] package.

6. That's it! The uImage and kernel modules you just built are saved in
`./build-area`. You just need to copy the files to your
already formatted SD card. For an easier way of getting the kernel on
your EV3, see [Sharing Your Kernel](#sharing-your-kernel). Starting with
ev3dev-stretch images dated 2018-05 or later, the uImage file is no longer
used. Create a Debian package as described in the *Sharing Your Kernel*
section.

~/work/ev3dev-buildscripts $ cd ./build-area/linux-ev3dev-ev3-dist
~/work/ev3dev-buildscripts/build-area/linux-ev3dev-ev3-dist $ cp uImage <path-to-boot-partition>/uImage
~/work/ev3dev-buildscripts/build-area/linux-ev3dev-ev3-dist $ sudo cp -r lib/ <path-to-file-system-partition>
6. That's it!

TODO: add instructions on how to modify uEnv.txt to use uImage file.

For now, see [Sharing Your Kernel](#sharing-your-kernel) for how to create
a debian package to install the kernel you just built.
