[GE users] launchd scripts on MacOSx Leopard servers

We have been using the launchd startup scripts from Bioteam for 6
months or so on a small cluster of Mac OSx Leopard servers. 
We have a relatively small cluster, compared to what I
have read about on this mail list, but they have worked
flawlessly through a number of system reboots of both execute nodes
and the qmaster node.  

We have run into some non-SGE related problems around the NFS
implementation in Mac OSx Leopard but nothing directly related to SGE
and the launchd scripts.
