Hmm, I've read that README, and I've read the 10- and 20- files themselves.
I never really asked anything about package dependenceis. It's pretty
obvious from the readme that 20 is an addition to 10, and as such requires
it. It's the hierarchical nature that the livecd-creator developer wanted to
create (Which is quite elegant and cool). Nevertheless, I really don't have a
a problem with package depenedencies.

Yes, I didn't ask about how it does things. That is obvious from reading the
script itself. I'm asking *why*. Because if one were to tell me that
/etc/init.d/livecd is created in 20 in order to configure the livecd when
it actually boots, I would say '"oh, ok. makes sense". But that doesn't
go well with the fact it gets deleted in the post) segment in 20. Not to
mention the fact that it really doesn't run in the post) segment per-se.
It just gets created using a "here document" clause. So when does
it actually run is what interests me, and why it's implemented like
this. I guess we'll just wait for someone else to explain it :)

 Not really, sorry. :)
We'll just wait for David. It's not that critical. I'm already working
and enjoying
livecd-creator. It just bugs me I don't understand that part.
Thanks a lot for the prompt replies!
