bb_daemonize_or_rexec(): add flag to double-fork; use it in start-stop-daemon
Add a DAEMON_DOUBLE_FORK flag to make bb_daemonize double-fork so it isn't a session leader, and hence doesn't get a controlling tty on Linux if a tty is ever opened, similar to how libdaemon's daemon_fork or the big start-stop-daemon does it - And use it in start-stop-daemon. For details, see http://www.win.tue.nl/~aeb/linux/lk/lk-10.html#ss10.3 Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
