phorm asks: "While there are newer many distributions of linux that come bootable from CD, I've found that some are a bit difficult to customize and wonder how hard it would be to create my own. Currently we are looking at replacing some of our Windows desktops at work with Linux test-machines - and it would be nice to make the installation process as simple as possible. How hard would it be to create a bootable CD that would automagically install Linux onto the first detected hard-drive? How would you go about 'imaging' an existing machine to use as the base? I suppose that in many cases a tar-gzip of the entire OS would work, provided you could partition the drive correctly, recreate some important handles as in /proc, and run lilo/grub to install a boot loader. Does anyone here have experience with this? I know morphix/knoppix make nice bootable distros but what I really want is a basic Linux bootCD which installs a preconfigured version of the OS of my choice."
