The stubs on the ESP are now input-addressed, where the inputs are the system toplevel and the public key used for signature. This way, it is guaranteed that any stub at a given path will boot the desired system, even in the presence of one of the two edge-cases where it was not previously guaranteed: * The latest generation was deleted at one point, and its generation number was reused by a different system configuration. This is detected because the toplevel will change. * The secure boot signing key was rotated, so old stubs would not boot at all any more. This is detected because the public key will change. Avoiding these two cases will allow to skip reinstallation of stubs that are already in place at the correct path. |
