# D.3. The ruby_init service `/etc/init.d/ruby_init`

The `/etc/init.d/ruby_init` service configures/ activates most of the settings specific to a Backstreet Ruby system.

    #	* handle commented out "PciOsConfig"

    #	- show config
    # 	- check wether curr. configuration matches setup ?
    #	- make it work when hotplug files not installed ?
    #	  ( currently it will just just inform that they are not installed
    #	  and exit )
