I know it may not be too interesting or relevant but it would be nice to have similar configurations for common/popular enterprise tools/platforms such as F5, Cisco, Juniper etc.

I see so many badly configured systems as part of the day job that it certainly would be great to help start socializing good configs.

PS. even for something like Tomcat (which changes features on minor versions?!?), it's hard to find good configs. I have a whole bunch of notes on things like this and happy to share if someone wants to codify it.
