I did not realize this, thanks for the extra information here.  That is
even more robust than I initially realized!

Ahh good to know this, I was just (incorrectly apparently) assuming this
is how the servers worked, based on the prescribed way you build them
locally to test them prior to uploading them to Launchpad (at least for
a PPA).  This is much more robust than I realized, thanks so much for
the clarification here.

Thanks for making this more clear here, I meant to reference the gpg key
of the repository being imported into apt (in this case the Ubuntu keys)
so that apt will know the source is trusted when communicating with it,
at least this is how I understand the process.

Yeah, I think gilir wrote the program used for configuring the session,
that is what I was remembering.

Yes, thanks for bringing the extra information here it is very
educational, and I really appreciate you taking the time to expand and
also to correct my misconceptions.
