Debootstrap and Multistrap - instructional material?

[Richard Owlett <rowlett@cloud85.net>]

I attempting to do some heavily customized installs. It was 
suggested I investigate
debootstrap. My initial attempts were only a partial success. 
While searching for more information I came across multistrap 
which appears more suitable for me.

The man pages and tutorials I've found so far demonstrate gaps in 
my background.

The material I'm looking for would likely have been prepared for 
formal coursework.

Suggestions?

Thank you
