Looking at the source, apt-cdrom does a bunch of checks and then calls
into pkgCdrom::Add()[1]. That does some more checks and then the
interesting stuff seems to start around line 746.
The Configuration Database (TODO: Find where this is stored... Ah, I
*think* that's the /var/lib/apt/cdroms.list mentioned earlier) is
checked for existance of the CD and updated, if necessary. The next
interesting part is at line 838 where the packages are copied. This
seems to happen in IndexCopy::CopyPackages()[2] which, at line 97,
creates a file in /var/cache/apt/archives/partial/ containing the
contents of the cdrom.
[1] http://sources.debian.net/src/apt/1.4~rc2/apt-pkg/cdrom.cc/
[2] http://sources.debian.net/src/apt/1.4~rc2/apt-pkg/indexcopy.cc/
So, in summary, I think you need /etc/apt/sources.list, /var/lib/apt
*AND* /var/cache/apt/archives.
