help
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.
