As a data point, last year I had such issues with one particular  
package. It was consistent no matter how often I was updating the  
ports tree. Poudriere always failed on port X which was depending on  
port Y (don't remember the names). The problem was, that port Y was  
build successfully but an extract of it was not having a file it was  
supposed to have. IIRC I fixed the issue by building the port Y  
manually, as re-building port Y with poudriere didn't change the  
outcome.

So it seems this may not be specific to the most recent ZFS version,  
but could be an older issue. It may be the case that the more recent  
ZFS version amplifies the problem. It can also be that it is related  
to a specific use case in poudriere.

I remember a recent mail which talks about poudriere failing to copy  
files in resource-limited environments, see  
https://lists.freebsd.org/archives/dev-commits-src-all/2023-April/025153.html
While the issue you are trying to pin-point may not be related to this  
discussion, I mention it because it smells to me like we could be in a  
situation where a similar combination of unrelated to each other  
FreeBSD features could form a combination which triggers the issue at  
hand.

Bye,
Alexander.
