It is configured by modifying 10 .Dq config.h 11 and recompiling the code. 12 .Ss Init sequence 13 By default 14 .Nm 15 will execute 16 .Dq /bin/rc.init . 17 You can chain your init scripts together at that point to allow for 18 single-user and multi-user operation. 19 .Ss Signal handling 20 .Nm 21 will respond to the following signals: 22 .Bl -tag -width xxxxxxxx 23 .It USR1 24 Default action is to initiate the shutdown sequence by 25 executing 26 .Dq /bin/rc.shutdown poweroff . 27 .It INT 28 Default action is to initiate the reboot sequence by 29 executing 30 .Dq /bin/rc.shutdown reboot . 31 .It CHLD 32 Reap children. 33 .El 34 .Ss General considerations 35 Running the 36 .Dq rc.shutdown 37 script directly is not recommended. If any 38 process in your session has stale filesystem references then it is 39 likely your init scripts will fail to unmount the filesystem cleanly. 40 It is recommended to signal 41 .Nm 42 via a wrapper script. 43 .Pp 44 .Nm 45 does not clear utmp records. The version of 46 .Xr getty 8 47 in ubase clears the utmp entries on the specified tty before it 48 spawns the given program, usually 49 .Xr login 1 . 50 .Pp 51 .Nm 52 does not restart 53 .Xr getty 8 54 or interact with it in any way. You will need an external 55 respawning mechanism to restart it. 56 .Sh SEE ALSO 57 .Xr killall5 8 , 58 .Xr getty 8 59 .Sh AUTHORS 60 The 61 .Nm 62 program was written by Dimitris Papastamos <sin@2f30.org>.
