The choice is between
* one parameter with the option being given as text within trigger file
* two parameters naming different types of trigger file
I don't mind which, as long as it is one of those two, unless there is a
third way to specify things so that user has control at failover time. A
single -m option would hardcode that decision ahead of time, which is
undesirable behaviour, hence the additional complexity being discussed.
