FreeBSD 16.0-CURRENT cf1eaaf41 Won't Install

I have been building CURRENT every two weeks for years using a fast PC 
and using NFS to install it on the others in my lab.  This is the first 
one that was built and installed successfully on the build machine but 
won't install on any of the others via NFS.

I tried installing base.txz from the last snapshot to see if anything on 
my existing system was missing but received this same result.  What tool 
or file on this PC needs to be found and re-installed if it's not in 
base.txz?
