Well, if you want to tell a program to discard its output, you tell it
to write to /dev/null. If you want it to read an empty file, you do the
same.
I get that it's not a good idea to do; however, I tend to think that
it's a bug.

Because I'm keeping track of the sources.list file myself. I read the
output of apt-cdrom, extract the sources.list entry from that, and
present it to the user. Later, if the user decides to keep the entry,
it gets written to sources.list.
It would seem that apt-cdrom is very uncooperative. It's not very easy
to control how CD-ROMs get added to sources.list outside of "open a
command line, type this magic...". But maybe I'm just using the wrong
tool. Do you have any recommendations?
