Why not have the shutdown script submit the DISABLE_SVC_NOTIFICATIONS
external command to Nagios and the startup script submit the
ENABLE_SVC_NOTIFICATIONS external command? Seems like a very
straightforward, service specific and workable solution, especially as
you seem to indicate that those scripts have access to your nagios hosts
file system (if it's NFS it probably won't work).
