.service_resource_providers ⇒ Object

This helper is mostly used to sort out the mess of different linux mechanisms that can be used to start services. It does not necessarily need to linux-specific, but currently all our other service providers are narrowly platform-specific with no alternatives.

NOTE: if a system has (for example) chkconfig installed then we should report that chkconfig is installed. The fact that a system may also have systemd installed does not mean that we do not report that systemd is also installed. This module is purely for discovery of all the alternatives, handling the priority of the different services is NOT a design concern of this module.
