Customised installer CD: Additional packages not seen by apt

["W. Borgert" <debacle@debian.org>]

Hi,

I managed to remaster a the sarge netinst CD following the hints
on http://wiki.debian.net/index.cgi?DebianInstallerModify, w/o
changing d-i or the kernel.  I just added packages in an "extra"
directory using apt-move.  Unfortunately, apt does not see the
packages in the extra directory.  The automatically generated
entries in /etc/apt/sources.list are:

deb cdrom:[Debian GNU/Linux testing _Sarge_ - Official Snapshot i386 Binary-1
(20050210)]/ extra/dists/testing/main/binary-i386/
deb cdrom:[Debian GNU/Linux testing _Sarge_ - Official Snapshot i386 Binary-1
(20050210)]/ unstable contrib main

If I change the first entry into a file entry it seems to work,
so I assume that my extra directory is not broken somehow.

Is there a something, I might have forgotton?  Does apt have
problems with multiple directories on one CD?

Many thanks in advance for any help!

Cheers, W. Borgert

Btw. why does the second line say "unstable", not "testing"?
