[updatenotification] use of this module creates pm2 daemon process(es)

[khassel]

When running mm with updatenotification module (or running tests where this module is active) we get

node@ec51cfe176dd:/opt/magic_mirror$ npx jest tests/e2e/env_spec.js

@bugsounet I'm not familiar with pm2, so my question is: Can we avoid these God Daemon processes?

[bugsounet]

sure it's not really logical to have 2 pm2 process running

I will inspect

(tested on my pi5, it's the same)

I don't create any process with PM2.
I just check pm2 app presence and check if MM² is on pm2 "status" list
--> if condition match set "flag" to use PM2 for restart MM² (with MM² process id in PM2)

So, i don't know why you have double process, maybe double install of PM2 ??? (I don't think PM2 must avoid this)

Thanks so far, will test this again ...
