Naturally, a lot depends on where you are working and your file
structure, but here is an overview of how I do it...
First, I build whatever the CD is going to look like on a seperate
partition, then mount that partiton on /mnt.
I use the following directories under one directory named `build`
boot - this will hold the initrd.img, also put syslinux.cfg, vmlinuz
(kernel), message.txt and optional syslinux.f1 and stuff in here.
rootfs - this is where I build the small root file system (you can use
an existing boot disk hor this)
syslinux - unpack syslinux in here
The script varies, but here are the big parts...
#define your variables
echo 'drive x: file="/tmp/livecd/floppyimage"' > $MTOOLSRC
dd if=/dev/zero of=/tmp/livecd/bootfile bs=1k count=6000 <=count varies
echo "y" | mke2fs -m 0 -i 1024 /tmp/livecd/bootfile
mount -o loop -t ext2 /tmp/livecd/bootfile /tmp/livecd/bootsrc
cp -a rootfs/* /tmp/livecd/bootsrc
dd if=/tmp/livecd/bootfile | gzip -v9 > ~/boot/initrd.img
dd if=/dev/zero of=/tmp/livecd/floppyimage bs=1k count=2880
mformat -t 80 -h 2 -s 36 x:
mount -o loop -t msdos /tmp/livecd/floppyimage /tmp/livecd/floppymount
cp boot/vmlinuz /tmp/livecd/floppymount
cp boot/message.txt /tmp/livecd/floppymount
cp boot/syslinux.cfg /tmp/livecd/floppymount
cp boot/initrd.img /tmp/livecd/floppymount
# and cp anything else optional (messages and stuff)
cp /tmp/livecd/floppyimage /mnt/boot.image
# make the CD
mkisofs -R -o cdimage.raw -c boot.catatlog -b boot.image /mnt
# edit this line for your speed and dev
cdrecord -v speed=4 dev=0,3,0 cdimage.raw
May need a little work to do what you want to do... there are other ways
of doing it -- this uses a loop device, I also have a script that makes
it in RAMDRIVE but I like this one.
