<p dir="ltr">You've misunderstood. I'm not attempting to decrease the serial number.</p>
<p dir="ltr">With inline signing you have a hidden serial number in the unsigned zone and an exposed serial number in the signed versions which your slaves track. After redeployment (following DR, emergency relocation, elastic capacity expansion, etc.) I want to be able to bump the exposed serial number (once) back to an appropriate value without having to modify the unsigned zones.</p>
