APT::Install-Recommends "0";

[Marco Möller <talby@debianlists.mobilxpress.net>]

(1)  I understood that setting the following parameter  in 
/etc/apt/apt.conf.d/myconfig  will have the same effect as manually 
using the flag --no-install-recommends  as in apt install 
--no-install-recommends somepackage .
  APT::Install-Recommends "0";
But how is this parameter respected if afterwards applying the following 
commands?
  apt upgrade
  apt dist-upgrade
Will the parameter also be respected?
I would expect that it will be respected and additionally no recoomended 
packages are drawn in.

(2)  If initially having had set the following parameter
  APT::Install-Recommends "0";
then having installed several packages,
then changing the parameter to
  APT::Install-Recommends "1";
what will happen upon the following commands?
  apt upgrade
  apt dist-upgrade
Will these commands now draw in the recommended packages?

(3)  If having installed a package with the following parameter, which 
status flag is set for the installed recommended packages after having 
used  apt install somepackage  and recommends additionally become 
installed?
    APT::Install-Recommends "1";
Will the additionally installed recommended packages be marked as 
"automatically" being installed, like a dependency, or will they appear 
as manually "installed"?

Greetings! Marco.
