And just a few weeks prior, I had given an update about this very issue, 
as per attached.

I figured if anyone needed more details (as I'd provided weeks prior), 
they'd reach out, like Bryan did.

Ummh, not sure if you need help reading, but my exact words were:

     "Probably could - but I'd prefer solutions that don't mess with the 
base
     system, which ensures long term usability of FRR across future 
upgrades."

The implication being that while it might work, it would make 
administration of the system onerous and unpredictable, considering we 
are dealing with a ton of FreeBSD installations, and not just a single 
server.

You, somehow, read my response is me being petulant; which is entirely 
your right, of course. But I also won't let you make a false inference 
of what my response actually was.

I made a statement, I was asked to explain, I did. There was historical 
context, even though I can't expect you to file all member's postings to 
memory.

But if you want to let yourself get into your feelings, I can't help you 
there.
