Create Amakha Live Cd

From Amakha

there are two way to have an amakha live cd iso image:

first using isolinux

• script is located in tools directory

cat ~/amakha/trunk/tools/scripts/create-iso.sh 
#!/bin/bash
#if [ "x$OEROOT"  = "x" ]; then
#    echo "Please run . ./tool/scripts/set-environment.sh from your amakha-root directory"
#    return 1;
#fi
ISOFS_DIR=$OEROOT/iso
IMAGES_DIR=$OEROOT/build/tmp/deploy/images/atom/
mkdir -p $ISOFS_DIR
cp /usr/lib/syslinux/isolinux.bin $ISOFS_DIR
cp $OEROOT/tools/scripts/stuff/isolinux.cfg $ISOFS_DIR
mkdir -p $ISOFS_DIR/boot
cp -L $IMAGES_DIR/bzImage-atom.bin $ISOFS_DIR/boot/vmlinuz && \
cp -L $IMAGES_DIR/image-atom.ext3 $ISOFS_DIR/boot/initrd.gz
cd iso 
mkisofs -o bootable-iso.iso \
       -b isolinux.bin -c boot.cat \
       -no-emul-boot -boot-load-size 4 -boot-info-table \
       $ISOFS_DIR

second using supergrub

• necessary tools:

download supergrub from here
ready compiled amakha-image-glibc-ipk-.dev-snapshot-20090916-atom.rootfs.ext3 and bzImage-2.6.30-r1-atom.bin

• preparing iso image

mkdir iso
mkdir iso/boot
mkdir iso/boot/grub
#extract supergrub and take necessary file
tar xvzf super_grub_disk_italiano_usb_0.9795.tar.gz 
cp boot/grub/stage2_eltorito iso/boot/grub
#take amakha files
cp amakha/atom/amakha-image-glibc-ipk-.dev-snapshot-20090916-atom.rootfs.ext3 iso/boot/initrd
cp amakha/atom/bzImage-2.6.30-r1-atom.bin iso/boot/kernel
#configure grub
echo "
default 0
timeout 5
title=amakha live 
root (cd)
kernel (cd)/boot/kernel
initrd (cd)/boot/initrd 
" > iso/boot/grub/menu.lst

• Create iso image using iso/ directory ad source

mkisofs -R -b iso/boot/grub/stage2_eltorito -no-emul-boot -boot-load-size 4 -boot-info-table -iso-level 4 -hide boot.catalog -o amakha.iso iso/

• Test with qemu

qemu -cdrom amakha.iso -boot d -m 256

• notes

livecd load all ext3 amakha filesystem in ram, you nead at least 200 mb ram to boot.
at boot time loading is slowly because before launch linuxrc script must be loaded in ram.
we should modify linuxrc script and create a new little initrd. 
At boot time linuxrc script  will mount the full-ext3-amakha-fs and exec chroot into it.
