# Idea is this:
#    1. we start testsuite-57-success.service
#    2. which through OnSuccess= starts testsuite-57-fail.service,
#    3. which through OnFailure= starts testsuite-57-uphold.service,
#    4. which through Uphold= starts/keeps testsuite-57-short-lived.service running,
#    5. which will sleep 1s when invoked, and on the 5th invocation send us a SIGUSR1
#    6. once we got that we finish cleanly

# Idea is this:
#    1. we start testsuite-57-prop-stop-one.service
#    2. which through Wants=/After= pulls in testsuite-57-prop-stop-two.service as well
#    3. testsuite-57-prop-stop-one.service then sleeps indefinitely
#    4. testsuite-57-prop-stop-two.service sleeps a short time and exits
#    5. the StopPropagatedFrom= dependency between the two should ensure *both* will exit as result
#    6. an ExecStopPost= line on testsuite-57-prop-stop-one.service will send us a SIGUSR2
#    7. once we got that we finish cleanly

# Idea is this:
#    1. we start testsuite-57-binds-to.service
#    2. which through BindsTo=/After= pulls in testsuite-57-bound-by.service as well
#    3. testsuite-57-bound-by.service suddenly dies
#    4. testsuite-57-binds-to.service should then also be pulled down (it otherwise just hangs)
#    6. an ExecStopPost= line on testsuite-57-binds-to.service will send us a SIGRTMIN1+1
#    7. once we got that we finish cleanly
