All third party repos should be used with care but the Atomic one is
known to contain many packages that overwrite core packages from the
CentOS base and updates repos without warning. Mere installation of the
atomic repo will proceed to update all those packages that are in that
repo and that also reside in CentOS base and updates repos unless the
end user has already configured yum-plugin-priorities to exclude
duplicates from lower priority repos. Not many first time users bother
to do this before they've been bitten once (or more!).

As an example, I went to
https://www.atomicorp.com/channels/atomic/centos/6/x86_64/RPMS/ and went
through the list of packages there and made a list of what's there. I
then ran

on my CentOS 6.6 system. As you can see from that command, I disabled
all other third party repos that I have installed so that only those
packages that are in the CentOS base and updates repos would be listed.
My command may contain typos and may also not be a complete list of all
packages there. For example there are lots of perl-* and php-* packages
in atomic that I could not be bothered to include because there were so
many of them so I omitted them but all of those have the potential to
overwrite core packages. The list I got back was as follows:

Last time I looked, yum used sqlite as a database so replacing sqlite is
a Really Bad Idea(tm). Replacing the distro php, mysql and various perl
packages is also not a good thing nor am I very keen on it replacing
libvirt nor do I look the look of many of the other lib* packages listed.

May I ask: do you work for atomicorp?
