I am talking about the CentOS Team .. The CentOS Project only tests
CentOS-7 (or CentOS-6) as the latest version with all updates installed.

We do not maintain any older versions .. so the only valid install is
the latest tree with a yum update run.

If you look on mirror.centos.org in any path other than the LATEST for
each major version, you will see this:

http://mirror.centos.org/centos/7.4.1708/

(that is from 7.4.1708 branch)

It says this:

========================================
This directory (and version of CentOS) is deprecated.  For normal users,
you should use /7/ and not /7.4.1708/ in your path. Please see this FAQ
concerning the CentOS release scheme:

https://wiki.centos.org/FAQ/General

If you know what you are doing, and absolutely want to remain at the
7.4.1708
level, go to http://vault.centos.org/ for packages.

Please keep in mind that 7.4.1708 no longer gets any updates, nor
any security fix's.
