Overview
brew can configure services to be started by launchd.
launchd identifies services by their "labels" (example: "com.apple.bluetoothd").

A program that was previously enabled to start at boot with launchctl enable can be prevented to start at boot with:
launchctl disable <name>
Start a Service
launchctl start <name>

System httpd keeps starting in foreground
I fixed with:
launchctl unload -w /System/Library/LaunchDaemons/org.apache.httpd.plist
but I don't know what determined it to suddenly start, and why the above command worked.
Is a Service Running?
launchctl list | grep com.something.someprocess
