%general-entities; ]> 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 started by init the TERM signal instead: cp src/init.c{,.orig} sed 's@Sending processes@& started by init@g' \ src/init.c.orig > src/init.c The following sed makes changes in the Makefile required for cross-compiling cp -v src/Makefile src/Makefile.orig sed -e 's@/dev/initctl@$(ROOT)&@g' \ -e 's@\(mknod \)-m \([0-9]* \)\(.* \)p@\1\3p; chmod \2\3@g' \ -e '/^ifeq/s/$(ROOT)//' \ -e 's@/usr/lib@$(ROOT)&@' \ src/Makefile.orig > src/Makefile Compile the package: make -C src clobber make -C src ROOT=${CLFS} CC="${CC}" Install the package: make -C src ROOT=${CLFS} INSTALL="install" install Sysvinit configuring /etc/inittab Create a new file /etc/inittab by running the following: cat > ${CLFS}/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 CLFS-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.
