Script Execution

As mentioned earlier, it is not always obvious when a particular service should be reconfigured. Should a daemon be stopped and restarted if necessary to force a reconfiguration? Or should we restart it during the night? Or should we wait until the next reboot? In practice, we never force a reconfiguration immediately whenever a specification changes (although this would not be hard to do). Those services which can be reconfigured while a machine is running, are normally reconfigured nightly by a cron job. Other services are reconfigured at boot time. It is possible for configuration changes to schedule a night-time reboot if it is essential that they are implemented as soon as possible.

A simple client-server application (om/omd) allows scripts on any remote machine (or group of machines) to be executed manually.
