37 With nonzero setting, init sends TERM, forks, child waits N
38 seconds, sends KILL and exits. Setting it too high is unwise
39 (child will hang around for too long and can actually kill
40 wrong process!)

Denis Vlasenkoa37e7132008-02-19 02:57:07 +0000[diff] [blame]47 If this option is enabled, init will try to give a controlling
48 tty to any command which has leading hyphen (often it's "-/bin/sh").
49 More precisely, init will do "ioctl(STDIN_FILENO, TIOCSCTTY, 0)".
50 If device attached to STDIN_FILENO can be a ctty but is not yet
51 a ctty for other session, it will become this process' ctty.
52 This is not the traditional init behavour, but is often what you want
53 in an embedded system where the console is only accessed during
54 development or for maintenance.
Denis Vlasenko2afabe82007-12-10 07:06:04 +0000[diff] [blame]55 NB: using cttyhack applet may work better.

87 This does not apply to initramfs, which runs /init as PID 1 and
88 requires no special support.
