Hi, Would someone kindly provide a real-world example of a service dependency? That is, some service "foo" that critically depends on another service "bar", and that satisfies either or both of the following conditions:
c1: service "foo" MUST NOT be started, or be attempted to be started, until service "bar" is running, lest something undesirable happens. c2: service "foo" MUST be terminated whenever service "bar" stops running, lest something undesirable happens. To elaborate a little, the following scenarios are of *no* interest to this inquiry: s1: service "foo" fails immediately on startup if service "bar" is not available. s2: service "foo" terminates itself whenever service "bar" is not available. s3: service "foo" successfully starts and runs even if service "bar" is not running, and waits or queues or times-out or retries with diagnostics while "bar" is unavailable, but otherwise does nothing undesirable in the absence of "bar". Many thanks, Wayne
