#
# - bar must not start until foo is ready
# - bar must be stopped when foo goes down
# - bar must be restarted when foo is restarted
#
# Regression test bug #314, that bar is not in a restart loop when foo
# is stopped. Also, verify that changing between runlevels, where foo
# is not allowed to run, but bar is, that bar is stopped also for that.
