The Message of the Day (MOTD) can be used to show system information at login time. For the Devopera family of modules, it shows a summary of host information (size/spec of machine), network setup (IP/MAC), what's installed (profiles and services) and exposed ports.

- rewritten for both CentOS and Ubuntu

- /etc/issue now dynamically generated from /etc/issue.template like motd.template
2013-05-08
- Added /etc/issue message to show IP/MAC address before login
In CentOS, the message of the day lives in /etc/motd. It is optionally updated from a template in /etc/motd.template by a script appended to /etc/rc.local. In Ubuntu, the message of the day is typically composed from fragments in /etc/update-motd.d/*. We therefore compose the motd in a temporary folder (/etc/puppet/tmp), optionally from a template in the same directory. update-motd.d/15-devopera-motd then displays content from that temporary folder.
Setup a simple informative message of the day at puppet-time
class { 'domotd' : }
Refresh frequently changing information at machine start-up (dynamics)
class { 'domotd' :
use_dynamics => true,
}
