It's not me or my mailer setting the Reply-To:.  It seems as if the 
mailing list is setting that on senders who's domain uses DMARC, which 
mine does.

I've added central... to my hosts file, so hopefully you can email me 
directly if you want to.

That's ... a different explanation than I've heard before.

I'm not saying I disagree with it, just that it's completely new to me.

Please elaborate.  Including using the same terms for both names.  How 
does "userland" compare to "base system" and / or "user interface"?

I'm also curious what differentiates between SunOS and a minimal install 
of Solaris.

I thought the "SunOS" vs "Solaris" was a marketing change around the 
time SunOS / Solaris transitioned from being more BSD to more Sys V.

I also thought that the retention of "SunOS" in the kernel name and 
versioning was for backward compatibility.

I was not aware that some of -- what I'll call -- the naming shenanigans 
happened to SunOS 4.  I was only aware of things at SunOS 5.
