[Koha] z3950-daemon-launch.sh

Well - we now have all our users in Koha! We are now beginning to input the books. All seems well, except for one thing. Each time the librarian shuts the machine down and up, I must redo the z3950-daemon-launch.sh. I know that the solution is to run the script from rc.local. I have made a link from the koha directory to usr/bin, and the script works fine from the command line as root. It just doesn't work from rc.local. I have tried placing the command at the beginning of rc.local and at the end. No luck. I have tried placing a ./ before it, and a sh before it. No change. Still it works great from the command line as root. Any clues as to where I am going wrong? Thanks! Robert Maynord
