-         One common problem reported on the mailing list is "can't access tty;
-         job control turned off" error message which typically appears when
-         one tries to use shell with stdin/stdout opened to /dev/console.
-         This device is special - it cannot be a controlling tty.
-
-         Proper solution is to use correct device instead of /dev/console.
-
-         cttyhack provides "quick and dirty" solution to this problem.
-         It analyzes stdin with various ioctls, trying to determine whether
-         it is a /dev/ttyN or /dev/ttySN (virtual terminal or serial line).
-         If it detects one, it closes stdin/out/err and reopens that device.
-         Then it executes given program. Opening the device will make
-         that device a controlling tty. This may require cttyhack
-         to be a session leader.
-
-         Example for /etc/inittab (for busybox init):
-
-         ::respawn:/bin/cttyhack /bin/sh
-
-         Starting an interactive shell from boot shell script:
-
-         setsid cttyhack sh
-
-         Giving controlling tty to shell running with PID 1:
-
-         # exec cttyhack sh
-
-         Without cttyhack, you need to know exact tty name,
-         and do something like this:
+         This option makes busybox shells to use $HISTFILESIZE variable
+         to set shell history size. Note that its max value is capped
+         by "History size" setting in library tuning section.
 
-         # exec setsid sh -c 'exec sh </dev/tty1 >/dev/tty1 2>&1'
