You can add it to the end if you want.

Otherwise at the next upcp the issue will reoccur again and send out more emails about being broken.<\/p>\n<p>cPanel&#8217;s official fix to this is slightly different. They state:\u00a0\u00a0&#8220;<em>The issue happens when the EPEL yum repo is enabled. A yum update installs the p0f package from EPEL instead of the cPanel provided p0f package. To correct this, you should added p0f*.el7.* to the excludes line in \/etc\/yum.conf, and ran \/scripts\/check_cpanel_rpms &#8211;fix to get the cPanel provided p0f package installed. Then you shouldn&#8217;t have this issue again.<\/em>&#8221;<\/p>\n<p>So please add &#8220;p0f*.el7.*&#8221; to the excludes line instead of just &#8220;p0f*&#8221; as this will prevent this from ever updating at all, while the former entry &#8220;<em>p0f*<\/em>&#8221; should only prevent it from updating from non-cPanel sources.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Hi all, &nbsp; I have been noticing quite a few issues relating to the cPanel p0f service crashing and sending e-mail notices to customers.
