[Bug 1730343] Re: firmware update breaks Ubuntu

[Mario Limonciello]

Thank for the feedback Koen.  Considering the failure there are other
intermediary patches causing problems in less obvious ways.

Since the "9" release is stable in all these other Ubuntu releases with
no other major complaints, I'm instead pulling in all changes to
efi/fwupdate.c from 0.5 to 9 release.

I've redone the upload for both packages, so it will be awaiting an
Ubuntu archive admin to accept it.

** Changed in: fwupdate (Ubuntu Xenial)
       Status: Fix Committed => In Progress

** Changed in: fwupdate-signed (Ubuntu Xenial)
       Status: Fix Committed => In Progress

Bug description:
  [Impact]

   * A few users have reported instances of not being able to boot into Ubuntu after a firmware update.  This is suspected to be caused by a missing Ubuntu boot entry.
   * fwupdate adds an entry for doing the update to the BootOrder, but doesn't remove it.  BIOS auto-creation for making boot entries typically depends on the BootOrder being empty.

  
  * This affects all releases of fwupdate since the code to add to BootOrder was
  also backported into the Ubuntu 16.04 release of fwupdate (0.5-2ubuntu5)

  [Test Case]

  * Perform a UEFI BIOS update after installing this package.
  * Ensure the system boots and there is no longer a "Linux Firmware Updater" entry
  present in the efibootmgr -v output.

  
  [Regression Potential] 

  * Regressions are possible to manifest if any BIOS depends on the
  previous behavior.

  * The fixes that were backported have been upstream for a few months and no
  concerns have been raised upstream from them.

  [Other Info]
  Two users have reported that fwupd breaks their Ubuntu installation because the "Ubuntu" EFI boot option disappears after an update.
