fiddling with livecd-creator

[subhodip biswas]

hi !
i have two questions. though unrelated still i asked them at once :
--------------------
i used  livecd-fedora-base-desktop.ks in order to built a live cd
using live cd creator . Now i am little bit worried about the packages
downloaded. Because it already did a 620 MB download. Have i done
anything wrong here.
I just needed a basic GNOME Desktop.
----------------------

One more question . Can Filesystem structure  be created within a
directory say /opt as in ltsp . if yes ..how ?
