Misc

• The Canonical Kernel Team is Hiring!
• We’ve updated the bcc snap based on the Mon August 28th tip commit: a91ec385fd1c5da.
• 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.
