To keep your server's operating system up-to-date, you may want to configure Auto-installer so as to notify you of new update packages available from your vendor. Note that Auto-installer will not install any packages without your confirmation, it will only notify you.
To have Auto-installer check vendor sites for updates:
.autoinstallerrc in the /root/ directory on the server, or, if you previously created this file, modify it. Add the following line to the file:ADDITIONAL_SOURCE="<type>, <priority>, <url>, <username>, <password>"
where you should replace <type> with repomd value, priority with a number from 1 to 999 (999 is the highest priority), and <url> with a URL of the vendor updates source. The values <username> and <password> are required only if your vendor's site requires authentication.
