DEV NOTES can you also add spawn? via function arg or something https://github.com/KomodoPlatform/Agama/blob/master/routes/api/daemonControl.js#L238 it's good for debugging/dev when you need to restart an app multiple times running native

@pbca26 Hi In this articles, it said spawn is fit for the long-running application. I think it makes sense so I switch to use spawn by default. Is there any case do you want to use execFile for running komodod?

i think it's a good idea don't forget to add detached option for debug purposes

@pbca26 Hi just added detached option. Please double-check and let me know if it's good enough for your case.
