these resource scripts have been written for heartbeat 1.x
(or the "non-crm" mode of heartbeat 2)
heartbeat _ignores_ the exit value for such scripts
for the "status" operation.
it only parses the output on stdout for "running".
if it contains that word,
the service is consisdered "running".
there also are "ocf" resource scripts and other stuff.
have a look if those suit you better.
