This chapter assume you use grub2 for your LFS. Issue the following to modify the file grub.cfg:
cd $LFSMOUNT
echo 'menuentry "LFS" {' > boot/grub/grub.cfg
echo " search -n -l $LFSLIVE -s" >> boot/grub/grub.cfg
echo " linux /boot/lfskernel root=LABEL=$LFSLIVE quiet" >> boot/grub/grub.cfg
echo " initrd /boot/initrd.gz" >> boot/grub/grub.cfg
echo "}" >> boot/grub/grub.cfg
Rename kernel, according to menu.lst:
mv -v boot/lfskernel-<version> boot/lfskernel
Where <version> is your kernel version
Create our ISO::
export ISODIR=<path to the dir where you want to store your ISO> cd $LFSMOUNT grub-mkrescue -o $ISODIR/livecd.iso -V $LFSLIVE $LFSMOUNT && unset ISODIR
Now, you can burn your image on a cd or dvd, and enjoy the livecd !
