You might want to try the Linux-from-scratch HOWTO or something similar if
you're truly adventurous. The best embedded demo I've ever received was the
one from QNX, but I don't believe theirs is Linux(though definitely *nix).
IMHO a DirectCD implementation is more of a pain than it's worth(see also in
this thread the part where someone discussed how their disk started
skipping/losing data at a certain temperature), especially when hard drives
are cheap.
Why make things harder than they have to be?
