Please create a yum repo for your AIX builds, so that AIX administrators may configure a yum repo to do zabbix agent installation and patching. 

Rational:

This helps to minimize the possibility that other updates will be installed that will break rpm only installed packages. This also saves time for and simplifies the AIX administrator's life, as they don't need to check the zabbix site for updates, ...., install it via rpm. Instead this would allow them the ability to automatically update it while doing a yum update, and if they wanted see that updates are available via commands like yum check-update.
