I have a feeling you're going to get into trouble trying this.

Most of those utils are provided by the coreutils package, which is a prerequisite for a million other essentials. I think you would have to start by building your own version of the busybox RPM, and adding a line to the spec file to tell it that it provides coreutils. That will avoid the dependency problems. It would also have to put symlinks to busybox in /usr/bin to replace all the missing commands.

Unfortunately, though, it's extremely likely to go wrong. Busybox packages generally don't provide all the same switches for the core commands; they often provide only the most important ones. Any package that relies on (e.g.) "mkdir -Z" will now fail. And my guess is that there will be hundreds of such failures, and they'll each give you a massive headache.

Busybox is useful for creating a completely custom-made setup, but not for replacing the core commands in an already existing setup.

Hello,

It seems when using livecd-creator command, it is using bash for installing package. There are 'busybox' and 'busybox-anaconda' packages from RHEL channel, is it possible to use busybox instead? Bash by default does not include commands like 'which', 'mkdir', etc, while busybox would have them built-in ..

Thanks,
