The Sysvinit package contains programs for controlling the startup, running, and shutdown of the system.

The following modifications help locate files specific to this perticular build: 

cp -v src/Makefile{,.orig}
sed -e 's,/usr/lib,/tools/lib,g' \
    src/Makefile.orig > src/Makefile

Compile the package: 

make -C src clobber
make -C src CC="${CC}"

Install the package: 

make -C src ROOT=${CLFS} install

7.6.2. Configuring Sysvinit

Create a new file ${CLFS}/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

EOF

The following command adds the standard virtual terminals to ${CLFS}/etc/inittab. If your system only has a serial console skip the following command: 

cat >> ${CLFS}/etc/inittab << "EOF"
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

EOF

If your system has a serial console, run the following command to add the entry to ${CLFS}/etc/inittab. 

cat >> ${CLFS}/etc/inittab << "EOF"
c0:12345:respawn:/sbin/agetty 115200 ttyS0 vt100

EOF

Finally, add the end line to ${CLFS}/etc/inittab. 

cat >> ${CLFS}/etc/inittab << "EOF"
# End /etc/inittab
EOF
