Sysvinit When run-levels are changed (for example, when halting the system), init sends termination signals to those processes that init itself started and that should not be running in the new run-level. While doing this, init outputs messages like Sending processes the TERM signal which seem to imply that it is sending these signals to all currently running processes. To avoid this misinterpretation, modify the source so that these messages read like Sending processes configured via /etc/inittab the TERM signal instead: sed -i 's@Sending processes@& configured via /etc/inittab@g' \ src/init.c A maintained version of the wall program was installed earlier by Util-linux-ng. Suppress the installation of Sysvinit's version of this program and its man page: sed -i -e 's/utmpdump wall/utmpdump/' \ -e 's/mountpoint.1 wall.1/mountpoint.1/' src/Makefile Compile the package: make -C src This package does not come with a test suite. Install the package: make -C src install Sysvinit configuring /etc/inittab Create a new file /etc/inittab by running the following: cat > /etc/inittab << "EOF" # Begin /etc/inittab id:3:initdefault: si::sysinit:/etc/rc.d/init.d/rc sysinit l0:0:wait:/etc/rc.d/init.d/rc 0 l1:S1:wait:/etc/rc.d/init.d/rc 1 l2:2:wait:/etc/rc.d/init.d/rc 2 l3:3:wait:/etc/rc.d/init.d/rc 3 l4:4:wait:/etc/rc.d/init.d/rc 4 l5:5:wait:/etc/rc.d/init.d/rc 5 l6:6:wait:/etc/rc.d/init.d/rc 6 ca:12345:ctrlaltdel:/sbin/shutdown -t1 -a -r now su:S016:once:/sbin/sulogin 1:2345:respawn:/sbin/agetty tty1 9600 2:2345:respawn:/sbin/agetty tty2 9600 3:2345:respawn:/sbin/agetty tty3 9600 4:2345:respawn:/sbin/agetty tty4 9600 5:2345:respawn:/sbin/agetty tty5 9600 6:2345:respawn:/sbin/agetty tty6 9600 # End /etc/inittab EOF Installed programs bootlogd, halt, init, killall5, last, lastb (link to last), mesg, mountpoint, pidof (link to killall5), poweroff (link to halt), reboot (link to halt), runlevel, shutdown, sulogin, telinit (link to init), and utmpdump Short Descriptions bootlogd Logs boot messages to a log file bootlogd halt Normally invokes shutdown with the -h option, except when already in run-level 0, then it tells the kernel to halt the system; it notes in the file /var/log/wtmp that the system is being brought down halt init The first process to be started when the kernel has initialized the hardware which takes over the boot process and starts all the proceses it is instructed to init killall5 Sends a signal to all processes, except the processes in its own session so it will not kill the shell running the script that called it killall5 last Shows which users last logged in (and out), searching back through the /var/log/wtmp file; it also shows system boots, shutdowns, and run-level changes last lastb Shows the failed login attempts, as logged in /var/log/btmp lastb mesg Controls whether other users can send messages to the current user's terminal mesg mountpoint Checks if the directory is a mountpoint mountpoint pidof Reports the PIDs of the given programs pidof poweroff Tells the kernel to halt the system and switch off the computer (see halt) poweroff reboot Tells the kernel to reboot the system (see halt) reboot runlevel Reports the previous and the current run-level, as noted in the last run-level record in /var/run/utmp runlevel shutdown Brings the system down in a secure way, signaling all processes and notifying all logged-in users shutdown sulogin Allows root to log in; it is normally invoked by init when the system goes into single user mode sulogin telinit Tells init which run-level to change to telinit utmpdump Displays the content of the given login file in a more user-friendly format utmpdump
