[Bug 1063061] Please test proposed package

[Adam Conrad]

Hello Steve, or anyone else affected,

Accepted mountall into precise-proposed. The package will build now and
be available at http://launchpad.net/ubuntu/+source/mountall/2.36.2 in a
few hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to
enable and use -proposed.  Your feedback will aid us getting this update
out to other Ubuntu users.

If this package fixes the bug for you, please change the bug tag from
verification-needed to verification-done.  If it does not, change the
tag to verification-failed.  In either case, details of your testing
will help us make a better decision.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance!

Bug description:
  [Impact]
  This is needed for full hardware enablement of 12.04 on SecureBoot systems.  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.
