Making a live CD
For those who don’t know, a Linux ‘live’ CD is a boot CD which contains a working linux installation. It allows you to run linux programs without installing linux onto the hard disk of the computer, much like a high tech boot disk.
I have toyed in the past with customising the gentoo live installer to work with PXE but it was mostly a hack. We had the need to create a live CD which has php and a custom php script. The solution was to build a real live CD, based on CentOS 4. CentOS recently released a live CD, and the build scripts but no instructions for building your own. I have figured out a procedure and here it is http://www.byteclub.net/wiki/CentOS_Live
