This is for the configuration of silo, similar to what is in bootscripts.

cat > ${LFS}/etc/silo.conf << "EOF"
# Begin /etc/silo.conf
partition = 1         # Boot partition (= root partition)
root = /dev/sda1      # Root partition
timeout = 150         # Wait 15 seconds before booting the default section

image = /boot/lfskernel-2.6.17.1
  label = linux
# End /etc/silo.conf
EOF

If you already have Silo installed on your target system, you do not need to reinstall it. Silo 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:

silo -f
