 * The Canonical Kernel Team is Hiring!
 * We've updated the bcc snap based on the Mon August 28th tip commit:
 * http://bugs.launchpad.net/bugs/1712168
   In Artful we enforce loading of only signed kernel modules under
secure boot. We support self-signing of modules by enrolling a MOK key
with shim and signing modules with that key. However a bug in our
4.12/4.13 kernels was causing the kernel to not use the MOK when
validating signatures. A fix for that has been comitted and will be in
the next artful-proposed kernel.
