I assume that this 'update' is a Fedora RPM? And it does not 'update'?
Your disagreement seems, to me, to be with Fedora or the Fedora
packager? The 'Generic' Mozilla Linux package, which is what I use,
updates as expected.

Did I "actually track  the exact state of the DigiNotar certificate"?
No. Not really. I just updated as needed and did not sit on my thumb
while the rest of the world solved this problem.

Have a nice day.
