- 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.
+ 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.
+ NB: using cttyhack applet may work better.
