Files managed by Salt should have a header stating this #148
Description
Ansible has a variable for this, ansible_managed. Salt does not. I suggest to add "This file is managed by SaltStack, all changes will be lost." in the first few lines of each template that fully manages a file.
Example: https://github.com/SUSE/salt-formulas/blob/master/bind-formula/bind/files/suse/named.conf
Edit: I noticed in the commit messages that you consider yourself not the upstream of the bind formula. From running a diff, I conclude that you consider https://github.com/saltstack-formulas/bind-formula as upstream, but there the SUSE version has custom features that are not upstreamed?
Lets use this https://github.com/SUSE/salt-formulas/blob/master/prometheus-formula/prometheus/files/general-rules.yml as example because with BIND, I should probably fix it upstream.
