> It's an old holdover from LSB compliance. *I* don't personally care one way or another, but it's supposed to be there for ancient scripts that look there to find out if a service is running. Probably none of those ancient scripts look for opensm as it wasn't around back when they were written and the "new and improved" way of checking a service in LSB is to run the init script with the status command. But, that's why I have it there. -- Doug Ledford <[email protected]> GPG KeyID: 0E572FDD http://people.redhat.com/dledford Infiniband specific RPMs available at http://people.redhat.com/dledford/Infiniband
