The LSB requires that any init script which is already running not do
anything when invoked with "start" when already started.
Many scripts ignore this requirement which the LSB standard imposes.
The short answer about why the old heartbeat infrastructure does this is
two-fold:
It takes care of some special cases involving resources moving from
one system to another and a system crash
It was the simplest thing to do. If the init scripts (aka resource
agents) conform to the LSB, it by definition
will hurt nothing.
