@windowsrefund You can already do this using TOFS, you can see this comment here for some background: #398 (comment). The whole discussion explains why the current template will have to be deprecated in the long term.

Essentially, just put any override files under any of the following places:

• salt/files/{{minion_id}}/minion.d/
• salt/files/{{os_family}}/minion.d/
• salt/files/default/minion.d/

Thank you very much.
