I have tried to create a livecd from Centos 4.4, it require to compile unionfs as a module. I'm using Centos kernel source kernel-2.6.9-42.EL.src.rpm and unionfs v1.1.5 but its giving error while compiling. http://mirror.linux.duke.edu/pub/centos/4.4/os/SRPMS/kernel-2.6.9-42.EL.src.rpm

Is anyone having success story building centos livecd from scratch?

There is a unionfs module that you can use already on the liveCD ... just copy it into place in the new kernel directory and do:

depmod -a

The version used on the liveCD is also in the tar file here: http://mirror.centos.org/centos/4/build/livecd/

I have tried to build using livecd-0.9.1.tgz, but it gives the error while booting the CD:

starting unionfs support insmod: cannot insert module '/tmp/unionfs.ko': invalid module format: (-1): Exec format error error inserting module unionfs (1) ...

I have followed README instructions, including compile unionfs againts current kernel (kernel-2.6.9-42.livecd.c4) and able to modprobe unionfs mannually.

The instructions seems different from the original linux-live script README: 1. it compile squashfs int kernel, while LL-script expect to find squashfs.ko (however from the boot msg, it seems able to load squashfs, no error) 2. it ask for different kernel version (ie `uname -r`_i686) 3. modify the existing linux isntallation (or do i ned to chroot before running build-livecd.sh -sl ?)

Many thanks.
