System V - Respawn service but don't launch at boot

I'm trying to have a System V service relaunched on exit. ***EDIT:*** Should have precised that I'm using busybox init system instead of classic systemV I found that It could be done using /etc/inittab with the keyword respawn as action (man inittab ). > respawn > The process will be restarted whenever it terminates (e.g. getty). This seems to be the right action to set, however with respawn the service will be launched at boot. I would like to have this service restarted but only after it has been launched from command line. **Is this possible to configure the service to respawn but not to be launched at boot ?**
