Add MOKx for blacklisting any specific hash of kernel module. For kernel module sign function, similar to dbx in UEFI, we need a MOKx for blacklisting kernel module that can avoid direct revoke the modsign key in MOK or kernel.

Gathering detailed information about hardware in an automated way with chef using an ohai plugin enhances transparency about the hardware being used in a datacenter. The idea is to write a plugin for ohai that gatheres information from hard drives used in a node that runs chef-client.

Moving objects to a new container is a problem everyone in R&D has faced at least once in his life. It requires a very advanced algorithm to pack the many different objects (which are generally heterogeneous, with different uses, types, weights and sizes), before the packs can then be transferred to the new container, generally through a dedicated bus. We can identify some usual cases: * In the worst case, the new container can be smaller than the old one, and a garbage collector is generally used to help find a solution that satisfies the problem (a SAT solver can be used to determine which objects should be destroyed).

The bootloader menu has to be able to list snapshots created with tagged attribute by snapper or other tools. These attributes control how snapshots are displayed and organized in the boot menu. All the changes are reflected in real time, that is when a snapshot is created it's ready to boot without the hassle to call grub2-mkconfig to refresh menu. The operation and navigating to the snapshot is intuitive and out of box and booting is even more easy to hit the button. The hackweek is based on current implementation to improve the code structure and testing, like code clean up and make it in better shape get upstreamed, improving the menu to use extended attribute to organize the boot menu with defined attributes which can be tagged by snapshot tools like snapper etc.
