The Creating custom facts recipe describes how to add extra facts written in Ruby. You can also create facts from simple text files or scripts with external facts instead.
External facts live in the
/etc/facter/facts.d directory and have a simple
key=value format like this:
Here's what you need to do to prepare your system to add external facts:
[root@cookbook ~]# facter facterversion 2.3.0 [root@cookbook ~]# facter -v 2.3.0
[root@cookbook ~]# mkdir -p /etc/facter/facts.d
