Package: apt
Version: 0.9.7.8
Severity: important
Justification: painful to debug problems

Hi folks,

I've just spent a very frustrating time trying to debug a CD build
problem, and apt-cdrom is very difficult to work with in these
conditions. While the automatic detection of CD drives is probably
very useful for most users, it's *insanely* annoying when you're
trying to debug a problem and don't want to have to write actual CD
images to test with. Doing this is very slow and potentially wasteful
of media.

As far as I can see, apt-cdrom was just ignoring me because it could
not find a CD drive on my machine via udev (nor in the VM where I
first started to debug). So, please:

(a) if apt can't find a CD to add for some reason, please *say so*
    rather than just saying "Repeat this process..." It currently also
    returns 0, suggesting even more that everything worked fine.

(b) add an option "Acquire::cdrom::UseUdev" or similar to allow people
    (me!) to disable the udev code and allow direct use of an
    already-mounted loopback ISO image or similar.

Thanks!
