Yes its etch official installation cd. I follow your suggestion and I
see one interesting difference betwen my build and the official from
ftp.debian.org. I change the priority and when is time to select d-i
components the official installation have a lot of components to load
than the my build, I have only 5 components to select.
Maybe this could be the awnser for why I cant install the files from CD.
How d-i manage that components? How I can include that "others"
components in d-i? Can debian-cd affect the components used by d-i?
The last question, I see one file called udebs.list in debian official repository. Is it needed?
