%general-entities; ]> Sysvinit Sysvinit-&sysvinit-version; contains a buffer overflow bug. Under some conditions, it modifies the values of environment variables. Fix this with: patch -Np1 -i ../sysvinit-&sysvinit-version;-proclen-1.patch 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 started by init the TERM signal instead: sed -i 's@Sending processes@& started by init@g' \ src/init.c Compile Sysvinit: make -C src 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 -I '\033(K' tty1 9600 2:2345:respawn:/sbin/agetty -I '\033(K' tty2 9600 3:2345:respawn:/sbin/agetty -I '\033(K' tty3 9600 4:2345:respawn:/sbin/agetty -I '\033(K' tty4 9600 5:2345:respawn:/sbin/agetty -I '\033(K' tty5 9600 6:2345:respawn:/sbin/agetty -I '\033(K' tty6 9600 # End /etc/inittab EOF The -I '\033(K' option tells agetty to send this escape sequence to the terminal before doing anything else. This escape sequence switches the console character set to a user-defined one, which can be modified by running the setfont program. The console initscript from the LFS-Bootscripts package calls the setfont program during system startup. Sending this escape sequence is necessary for people who use non-ISO-8859-1 screen fonts, but it does not affect native English speakers. Installed programs halt, init, killall5, last, lastb (link to last), mesg, pidof (link to killall5), poweroff (link to halt), reboot (link to halt), runlevel, shutdown, sulogin, telinit (link to init), utmpdump and wall Short descriptions halt normally invokes shutdown with the -h option, except when already in run-level 0, then it tells the kernel to halt the system. First 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. Init 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 won't 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 show 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 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-friedly format. utmpdump wall writes a message to all logged-in users. wall
