Fixing init.d to allow for custom log file

In its current state, you cannot add a custom logfile to the server instance because the code is set in such a way that the home directory is always in front of it. 

By taking that variable and adding it to the log_file attribute, you can edit it to be the full path to a logfile elsewhere. 

The reasoning: the file grows very quickly and could consume disk very quickly if it is on a small file system.
