Please don't trim the log output. You can also use -d to get more output.

This is only correct if the old certificate was self-signed. Otherwise it must
be the old root CA certificate.

If your using intermediate certificates, the new-certificate-1.pem can't be
self-signed. Accordingly, using it as the --signing-keyring can't be correct.

You need to use the *new* root CA certificate here.

It uses the same code paths as the normal bundle creation for singing, so I
don't see why it should behave differently.
