Create a aboot.conf file defining aboot's boot menu:

cat > ${CLFS}/etc/aboot.conf << "EOF"
# Begin /etc/aboot.conf
0:1/boot/clfskernel-2.6.17.13 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 when you can boot, you will need to issue the following command:

swriteboot -f3 /dev/sda /boot/bootlx
abootconf /dev/sda 1
