What format is the images/pxeboot/initrd.img file on the DVD ?
Its not gzip its not straight cpio
What is it? I wish to change it.
I'm finding information on changing the gzip version of initrd but not the PXE one.
If I do "file initrd.img" it just says data.
Thanks,
Jerry

$ file initrd.img initrd.img: LZMA compressed data, streamed
That may give you a hint.

I ran into this also. It's compressed using xz. You will probably need to be on an rhel6/centos6 system to manage the image.

Just grab the xz package.
I roll initrds (for a custom pxe boot setup) on a CentOS 5.8 host. I've rerolled the initrd for 6.2 some time ago and you've reminded me to take care of 6.3 today.

If you're updating your CentOS 5.X installation regularly at all, xz and xz-libs should be automatically downloaded as a dependency for something, can't quite remember what. Most of our 5.X machines have pulled it when updates are run weekly.
