How to install Centos 6.9 minimal with minimal packages?

Question

CentOS

Trying to install Centos 6.9 x86_64 minimal. The graphical installer opens, in the process it stumbles on something, says that it does not find some file in the installer. I initialize the interface, specify an http link to Centos 6.9, to vault.centos.org. The installation silently completes installing a mountain of unnecessary packages, including the graphical environment.
How to force the installer not to put absolutely nothing but @core?

Answer 1

6.8 you will not deliver. Put 6.9.

Answer 2

Try downloading the distribution. And check the amount.

Answer 3

I created a response file, uploaded it to a USB flash drive, clicked on the exit of the primary menu <tab>, addedinst.ks=hd:/dev/sdb1:/ks.cfg

%packages --nobase
@core
%end

All the same, dozens of groups of packages were installed. Centos maintainers are inadequate.
