New project: Nagios on BeagleBone Black

Here is my new project. It is not really an embeded project but it is on an embeded platform.
Today I'm using an HP MicroServer in my office as Nagios server. I'd like to change it to a BeagleBone Black what I recently purchased.
The process should be the following:
- Install Ubuntu Server to the BeagleBone (12.04 LTS or 13.04)
- Install nagios
- Move configuration files
- Done
