Hi,

I've made a site\_facts module that adds some facts I use in my  
playbooks. I'm also using tags to sometimes run subsets of my  
playbooks, which I believe is the primary motivation for tags. My  
problem comes in when I want to use some of the facts added by my  
site\_facts module when running only a subset of my tasks. For  
example:

You could tag it with ‘facts’ and always remember to include the ‘facts’ tag.

I have a similar issue, though not totaaly related. The extra facts are things I can calculate ofline (primarily network information, ip addresses, based on a preconfigured vlan), without touching the hosts first. I hope to solve this with an inventory plugin.
