How to save configuration modifications on Asterisk@Home?


I make configuration modifications on my PCBX Asterisk@Home and I want to save these modifications.

How to saves these modifications???

I type :
“service gnugk stop” to stop my gatekeeper
"service gnugk start" to restart my gatekeeper
"asterisk -r"

These commands are sufficient to save my new configuration?

I am a beginner…

Thanks for your help…
