Bug description:
[SRU Justification]
== Impact ==
The build of AWS kernels currently is set up in a way that, like the
generic kernel, builds a larger number of modules than it actually
provides in the main modules package. However, unlike the generic
kernel, it does not provide a linux-modules-extra which contains all
those built modules.
So there is no way for users to get modules which were deemed
unnecessary in the AWS cloud space. But this also causes problems in
cases where out of tree modules are being tried to compile. Those will
configure themselves based on the provided config and then might
depend on functionality which is provided in some module that is not
part of the non-extra set.
== Fix ==
To fix this, but also to get all of the kernels aligned, the AWS
kernel should start to provide a linux-modules-extra which contains
all those modules not shipped in the main modules packages. Since the
default linux-aws meta package is supposed to only install the minimal
set, there needs to be a linux-modules-extra-aws meta package which
keeps the extra modules in sync with the kernel.
== Testcase ==
sudo apt-get install linux-modules-extra-aws
This should download and install additional kernel modules.
== Risk of Regression ==
Low, this will start to ship an additional package which is not
installed by default.
