patches vs sed

I find a much better way to do LFS is to have GPM running in the console 
- first I read over the commands and understand what they're doing, then 
just copy and paste to the building prompt with the mouse. I realise 
that LFS shouldn't be simply mindless copying of commands, but
a) that can actually be a good way to learn at first - to just blindly 
paste and see everything working, and then start to understand how it 
all functions, and
b) if I understand it already, then there's no sense in wasting huge 
amounts of time copying all the commands in.

Again, just MHO :D
