I'd like to propose an nginx configuration management. Please, check: https://github.com/renich/fedora-configs/tree/nginx

Basically, it uses a conf.d to store additional configuration for the nginx.conf file.

Then, conf.d contains servers.conf; which includes everything on server.d.

Then, the server.d files consume include.d; which has modular configuration to add support for, say, wordpress, zendframework, etc.

The architecture is, yet, to be improved, but, IMHO, it is much better than the sites-enabled/sites-available configuration.

Let me know if interested and I can help with integration.
