Bug Description
The efivarfs driver in the saucy amd64 kernel is built as a module instead of being built in. As a consequence, when mountall checks /proc/filesystems to see what optional filesystems are supported, it doesn't find efivarfs there and efivarfs is never mounted at boot. This in turn means that secureboot-db will not be able to apply secureboot database updates to firmware, potentially leaving systems vulnerable to boot exploits.
This used to all work in raring and earlier, where efivarfs was built into the kernel (which was the only option). Please fix the config to make efivarfs built-in again (CONFIG_
For reference, please note that any kernel filesystem that mountall has flagged as "optional" in /lib/init/fstab must be a built-in driver in order to get the correct results. In addition to efivarfs, this includes debugfs, securityfs, spufs, binfmt_misc, and fusectl.
