Bug description:
  [Impact]
  security update staged in updates

  [Test plan]
  Boot it on multiple systems. Notably juliank will be doing semi-automated testing in QEMU that does chainbooting over network (shim->grub->shim->grub); and boots on T14 G3 AMD and an XPS 13; chrisccoulson did his own security testing before that.

  [Where problems could occur]
  Font loading is disabled, could cause rendering issues

  Unicode font stuffed in xz squashfs, could cause more memory issues
  during boot
