As I understand it, if I embed GPL licensed code into my application, then I would be compelled to furnish the source code (or at least make it available to them) to any customers.
My question relates to a slightly different scenario. What if my application was, for example, a control panel that installs and manages various different web services (e.g., Postgres, Apache, HAProxy, etc). If one of those web services was GPL licensed (HAProxy is GPL v2), would I then be required to provide the source code of my control panel to my customers?
My hypothetical software can't function without the installation of GPL licensed packages, but the source code of the GPL licensed packages is not embedded in my source code.
