This seems the best option, although none are great - build with `make AUFS=1` to build with AUFS support, currently with 4.8 kernel - default is to build without AUFS support, with 4.9 kernel This recognises that AUFS supprot is temporary #620 and only there until we can phase it out on desktop editions, and allow the other editions that never shipped with AUFS to ship something very close to mainline. However we do still apply the patches so that the non AUFS branch runs fine on all platforms, so it can be tested elsewhere. We may be able to move the kernel versions back in line when 4.9 aufs support is out. Plan is to shift CI to build both sets of images, and get the Desktop editions to pick up the aufs set automatically, once this is merged. Signed-off-by: Justin Cormack <justin.cormack@docker.com>
Temporary non modular kernel config for pinata alpha
TODO: build with Alpine and/or use Alpine kernels - needs some patches.
The build is mostly silent. To view the output use docker log -f <containerid>. The build creates multiple containers, so multiple
invocations may be necessary. To view the full build output one may also invoke docker build . and then copy the build artefacts from the image afterwards.
To build with various debug options enabled, build the kernel with
make DEBUG=1. The options enabled are listed in kernel_config.debug. This allocates a significant amount of memory on boot and you may need to adjust the kernel config on some systems. Specifically:
