[Julian Andres Klode]

The opposite, it only reads the mirrored ones, soon to be replaced by
config table.

Title:
  Mirrored MOK variables could be accidentally deleted

Status in shim:
  New
Status in shim package in Ubuntu:

Bug description:
  [Impact]
  On some systems, Mok variables mirrored are accidentally deleted after the mirroring. This can prevent the kernel from loading DKMS modules, if it does not yet use the config table to parse the MokList variable; and userspace tools relying on the variables will have wrong results.

  Most implementations reject the accidental delete, as the flags do not
  match, this bug was produced on VMWare.

  [Test plan]
  If we can get a VMWare Workstation or Player license, it would be good to validate that. Without a license, the best we can do is ensure there are no regressions on other machines and rely on the authors of the patch (SUSE) to have tested this properly.

  [Where problems could occur]
  We could accidentally delete the variable on other systems now.
