Hi,

CentOS users have easy access to the EPEL repo because the epel-release RPM is in the CentOS Extras repository. Obviously CentOS and EPEL have a special relationship, since they are both sponsored by Red Hat. A coworker suggested to me that it would be nice if the ius-release RPM could be included in Extras as well. I brought the idea up in IRC, and Karanbir suggested I draft up a specification that any third party repository can follow to be considered for inclusion. Here is what I have so far.
From above text.
* Must not automatically install, upgrade, or replace stock distribution packages when the repository is enabled.
Problem: lot of packages is repositories following this RFC provides the same "virtual" to be able to be a drop-in alternative for base packages.
Ex:
$ rpm -qp --provides php-mysql-5.3.3-40.el6_6.x86_64.rpm php-mysql = 5.3.3-40.el6_6 php-mysqli ...
$ rpm -qp --provides php56u-mysqlnd-5.6.7-1.ius.el6.x86_64.rpm php-mysql = 5.6.7-1.ius.el6 php-mysqli = 5.6.7-1.ius.el6 ...
What happen if someone (or a package dep.) try to pull php-mysqli ? Yum is unable to select the correct package.
So the rule, from the RFC is not honored.
More, there is a lot of 3rd party repository, most of them are not designed to be compatible with others (usually only with base + epel).
Sometime, users install a lot of these 3rd party repositories, and create terrible mess in their system. If CentOS is going to add "some" 3rd party repositories configuration, I think this will encourage users to enable them, and thus result in more mess.
Remi.
P.S. exemple of such issue, on an fresh C6 installation:
