I saw a paper, recently, that showed a step-by-step method of opening 
a CD or DVD installer, on a partition, making the invisible files 
visible, lining them up in their proper hierarchy (which is already 
'done' for the most part), and then choosing the 'lean' system to 
reboot from, thereby allowing a reboot off what was an iso.

I'm searching high and low for the actual text, it was only about ten 
or twelve steps. Simple, but not something one would do impatiently.
