This is my first init script, so far, it atleast starts the daemon but it fails at creating a pid, so later on I can use to, to either stop it or reload it. Here's the current code:
Further more, the script returns ok that it started the pid, when in fact, the pid fails in the background, this script needs MUCH improvement, some help would be nice to fix this script. :/
Code:
