[Bug 1924605] Re: Grub2 menu not loading - could not create MokListXRT: Out of Resources

[Julian Andres Klode]

** Description changed:

+ [Impact]
+ Systems fail to mirror MokListXRT. We've taken measures to reduce the size of the variable, and also made one spot non-fatal when running on non-secureboot systems that was fatal before which should address those issues. Also see related bug 1928434.
+ 
+ [Test plan]
+ We do not have tests to verify this
+ 
+ [Where problems could occur]
+ See bug 1928434; and also the point where we make it non-fatal only changes code path on non-secureboot systems, so there is an easier workaround if they fail to boot anyway. Although, it literally just adds an `|| efi_status == EFI_OUT_OF_RESOURCES` as non-fatal condition.

  Ubuntu 21.04 (ZFS)
  Dual boot: Ubuntu and Windows 10 on separate drives
  
  Steps to reproduce:
  
  * system update using 'apt update' in terminal. I have attached apt log file. The problem appeared after 'Start-Date: 2021-04-15  19:40:02', last entry.
  * 'zsysctl service gc -vv' - to remove unnecessary states
  * restart the system
  
  Outcome:
  
- * Grub2 menu does not show. Instead, error messages appear: 
+ * Grub2 menu does not show. Instead, error messages appear:
  'Could not create MokListXRT: Out of Resources'
  'Failed to set MokListXRT: Out of Resources'
  * After 10 sec Ubuntu starts (Ubuntu was previously set as default system)
  
  Expected outcome:
  * Grub2 menu with Ubuntu, Windows and recovery options
