The Precise Pangolin has reached end of life, so this bug will not be fixed for that release

Without this change, management of the SecureBoot revocation database is not possible from Ubuntu userspace (at least, not out of the box). [Test Case] On EFI-enabled hardware: 1. verify that /sys/firmware/efi/efivars is not mounted at boot time. 2. install both linux-image-generic-lts-quantal and mountall from proposed. 3. reboot. 4. verify that /sys/firmware/efi/efivars is now mounted. [Regression potential] Minimal; as this uses mountall's notion of 'optional' filesystems, the filesystem will simply be skipped if the mountpoint does not exist or the filesystem is not supported by the running kernel. As of Linux 3.5, it is not possible to update the SecureBoot database from userspace because the sysfs implementation only supports variable data up to 1KB in size and this is exceeded by even a minimum key database of one key. Matt Fleming has accepted a patch from Matthew Garrett to add a new filesystem that supports larger variables. Please consider backporting this (as an SRU) to both quantal and precise. https://lkml.org/lkml/2012/10/5/22 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1063061/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
