Create an aboot.conf file defining
aboot's boot menu:
cat > ${CLFS}/etc/aboot.conf << "EOF"
# Begin /etc/aboot.conf
0:1/boot/clfskernel-3.4.17 root=/dev/sda1
# End /etc/aboot.conf
EOF
If you already have aboot installed on your target system, you do not need to reinstall it. aboot is just a chain loader and has no bearing on the system build.
After you get the build copied to the system that it will boot from, you will need to issue the following command:
swriteboot -f3 /dev/sda /boot/bootlx abootconf /dev/sda 1
