Your install script is simply obnoxious - it is in a shell archive and it does way too many nasty things like editing the sources and nuking eth0.  It is too buggy to be a black box like this.

Is there documentation anywhere on how to get things going?  The latest problem I have is that it wants to re-copy the entire install CD every time I run the install, even though it has already archived it on the local file system.

Thanks,
Mark
