-	  If this option is enabled a command starting with hyphen (-)
-	  is run in its own session (setsid(2)) and possibly with a
-	  controlling tty (TIOCSCTTY).  This is not the traditional init
-	  behavour, but is often what you want in an embedded system where
-	  the console is only accessed during development or for maintenance.
+	  If this option is enabled, init will try to give a controlling
+	  tty to any command which has leading hyphen (often it's "-/bin/sh").
+	  More precisely, init will do "ioctl(STDIN_FILENO, TIOCSCTTY, 0)".
+	  If device attached to STDIN_FILENO can be a ctty but is not yet
+	  a ctty for other session, it will become this process' ctty.

+	  development or for maintenance.
 	  NB: using cttyhack applet may work better.
