Unfortunatly, netselect isn't always going to be available. I'd love to use
it.
Grouping the mirror list by country is still useful despite what you've said.
If you're in Canada and know the US is going to be faster, then you select
the US off the list. If you're in the US and know connectivity to australia
sucks, you know the one item _not_ to choose is Austrialia. In either case,
you've made a more informed decision than picking one item at random off a
long list of choices.
I did make the US the default of course.
It's worth noting that the debian mirrors web page
(http://www.debian.org/misc/README.mirrors) is ordered by country, and
indeed I think that's why you include the country data in Mirrors.masterlist
in the first place, right?
I can tune the description to be something like:
Description: Select a country
Select the country the mirror should be in. The goal is to find a mirror that
is close to you on the network, and be aware that near countries, or even
your own, may not be the best choice.
.
If you want to enter mirror information manually, select the last item on
the list.

I'll talk to the boot-floppies folks and make sure new cd installs come with
a fstab line for /cdrom. Unless I'm missing something, this will make
apt-get work.
The reason I'm using --no-mount is because I don't want apt-cdrom to prompt
for the cdrom to be inserted, since my own prompts already ask that that be
done, and so the autoprobing can happen without user interaction.

True, removal would be a nice thing to have. I'd be happy to add it in the
future.

Ah yes I meant sources.list and I'm querying apt-config for that now.
Apt-cdrom dump doesn't seem to output a location of apt-get or apt-cdrom,
and besides, I don't care where they are as long as they're in the path.

Oh, I read too fast. The filenames (which mutt *does* preserve in its mime
messages, I wonder if the BTS screwed it up?) were setup and
setup.templates.

That is truely strange. Where did you put it, and how did you modifiy the
script and did it give error messages to stderr about it?

Yes, it probes for cdrom on startup -- the boot-floppies people want that to
smooth the setup process for people who have just installed from cdrom. That
should be turned off when it's being run from dpkg (done).

I don't see how this could fail to notices apt's return code. Do you? Are
you sure apt failed?

Randomly? Debconf sizes the dialog to the text that is inside it.

Which is logical is debatable..

Well you said it "insisted in writing invalid urls", I still don't have
details of that.
