add to each enabled section a @priority@ setting equal to @10@

<pre>

[base]

name=CentOS-$releasever - Base

mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os

#baseurl=http://mirror.centos.org/centos/$releasever/os/$basearch/

priority=10

h2. Test

actually not a test, but this one-liner gives you a sorted output of repo's and their configured priority

<pre><code class="bash">

sed -n -e "/^\[/h; /priority *=/{ G; s/\n/ /; s/ity=/ity = /; p }" /etc/yum.repos.d/*.repo | sort -k3n

</code></pre>

should give you a output like

<pre><code class="bash">

priority = 10 [base]

priority = 10 [updates]

priority = 20 [virtualbox]

priority = 30 [rpmforge]

priority = 40 [epel]

priority = 100 [adobe-linux-x86_64]

</code></pre>
