Hi,
just some script built along: Unattended install & run CentOS-4.1 just using
chroot(1). Mostly a surprise for me it was so easy to reach that goal.
It requires rpm(1) based host OS and it was tested only on Fedora Core 4.
I needed it to do only a bit customized CentOS kernel package rebuild.
Regards,
Lace
