Bug Description

Currently, when updates that require a restart are done (ie: linux-kernel), the user is advised to do a full system restart for these changes to be effective.

Instead of doing a full restart as currently done, the user can be prompted to restart using kexec, to avoid the BIOS/firmware stage of the reboot process, hence achieving the same result in far less time (some motherboards have a aditional chipsets that initialize sata/raid drives, that can add up to 15 seconds to reboot process.

GRUB parameters can be detected and passed onto kexec, resulting in a far faster "reboot".
