It'll use start-stop-daemon to start daemon and check that pidfile was
created.
Allow user to override user that will be used to run pm2 daemon. As a
consequence install init script with pm2 name instead of pm2-root.
Provide some information on how to start services aftewards.
Make reload function working.
* It should only log rotate on log files
As explained in https://github.com/Unitech/pm2/issues/2498#issuecomment-263678535 :
The logs are being saved as index-out-0.log and index-error-0.log.
If you just leave /home/user/.pm2/pm2.log /home/user/.pm2/logs/*, the first time logrotate runs, it generates index-out-0.log.1. The second time it runs it generates index-out-0.log.1.1, and it continues creating files for each file found, since you are including all files.
It should be reverted back to *.log or *log
