 Options are modifiers to services.  They affect how and when init

+  This service needs a console. The optional second parameter chooses a

+  be changed by setting the "androidboot.console" kernel parameter. In
+  all cases the leading "/dev/" should be omitted, so "/dev/tty0" would be

   This is a device-critical service. If it exits more than four times in
   four minutes, the device will reboot into recovery mode.
