Hi,

I received a message with Subdject : "Cron <root@hosting> yum -y update" and body:

Loaded plugins: fastestmirror
Setting up Update Process

* extras: mirror.bg.host.ag
* rpmforge: ftp.lug.ro
* updates: mirror.bg.host.ag
* webtatic: uk.repo.webtatic.com

What is this message?
I needs you to do something?

This command will check for os and app updates..

Does this mean that it is checked for updates and those discovery are updated to the latest version?
