There is a good chance I am wrong and I am sorry for that
(my first language is french-canadian so sorry if something does not make sense)
but I really think there is something wrong.

1)
for every version SL or CentOS systems (that are not yet 76) having elrepo
enabled will cause a failure if we try to install or update nvidia-340xx

% yum --enablerepo=elrepo install kmod-nvidia-340xx

...

2)
I did try to be more specific but it failed anyhow... I tried every possible
combination.

    % yum --disablerepo=\* --enablerepo=elrepo install kmod-nvidia-340xx-340.107-1
    % yum --disablerepo=\* --enablerepo=elrepo install
    kmod-nvidia-340xx-340.107-1.el7_5
    % yum --disablerepo=\* --enablerepo=elrepo install
    kmod-nvidia-340xx-340.107-1.el7_5.elrepo.x86_64
    % yum --disablerepo=\* --enablerepo=elrepo install
    kmod-nvidia-340xx-340.107-1.el7_5.elrepo.x86_64.rpm
    No package kmod-nvidia-340xx-340.107-1.el7_5.elrepo.x86_64.rpm available.
    Error: Nothing to do

    then *you saying this made me wonder* ... so I cleaned yum cache and it
    worked without the .rpm (which still fail)
        yum clean all
        yum --disablerepo=\* --enablerepo=elrepo install
    kmod-nvidia-340xx-340.107-1.el7_5.elrepo.x86_64

    great one thing solved. next,

exclude=*el7_6.elrepo*       yes does work for now.

Although it does work it require us to reconfigure several hundred of systems
and change a repo config file on all system that may be power on or off.
We also need to prevent issues for future version and in example el7_[6,7,8,9]
and instead of excluding 7*6 is there a way to include ONLY *7_5* ? (for EL75
systems)

4)
I think
Having elrepo to be directly available by major and minor version would be a way
to fix this and it as Nothing that I now to do with CentOS.
Scientific Linux repos are provided to be accessible by major and minor version
7.3, 7.4 , 7.5  or latest 7x version if we want.
So a system running 7.4 or 7.5 will not update to 7.6 unless 7x repo is made
available on that system.

Sorry to insist but this update does fail all your CentOS and Scientific Linux
user.
Releasing el7_6 update is an impossible version to us - all clone users.

I have been using elrepo for years but I am new on the list ...
I do fail to see the new way that *now PREVENT* from braking systems...
To me the way it is configured now does brake systems because EL7_6 is made
available to all EL7.4 and EL7.5 systems.
errors are  liste in 1).

What is supposed to be updated that is not ?

Please tell me what am I missing here.

best regards,
Rejean.
