- Add back Linux kernel 4.4.x support, only for AUFS at present. - Add back config options that are different for 4.4 series See #923 for discussion on whether we need to do this. 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:
--- a/alpine/kernel/kernel_config
+++ b/alpine/kernel/kernel_config
