Given the passage of time, I'm not sure you were right. :-)

This integration work is now done.

No change at this time.

I've been spending the last week reading discover source code and
thinking of a solution for this.
The problem with the command line you describe is that the data format
has changed in a fundamental way, and there are now ways that a command
line as you describe won't give you the data you want. In a narrow
sense, that isn't going to be true now, but it could be. What we need
to decide is if this is a problem or not, or whether there's a better
There are a lot of issues that need thinking through now, but as you
have described it, we don't really have time right now for that. So,
I'm going to meet you half way, and leave the deep thinking for later.
I am in the middle of preparing new discover 2 packages (and
discover-data as well) and placing them in the same place they were
before. Again, these are very preliminary, so please don't distribute
them as "final" 2.0.2. These should be ready tonight sometime.
Inside the discover-udeb package, you will find a new utility,
"didiscover". (Think "Debian Installer discover". Sorry if it's a bad
name; as Branden will tell you, naming is not my strong suit.) This
utility is nearly exactly the same as discover, but with one additional
feature: you can now tell discover to output vendor and model
information as part of the format string.
So, to do the equivalent of this discover 1 command line:
/sbin/discover --format="%m:%V %M\n" ethernet
you'll do this with didiscover:
/usr/bin/didiscover --data-path=linux/module/name --data-vendor --data-model \
--format="%s:%s %s" network
Please give this a try and let me know if it works for you. (Backslash
handling, such as "\t", doesn't seem to be there in either discover or
didiscover, but it should be fairly straightforward to add if
necessary.) If the name is troubling to you, we can kill off the copy
of discover in the udeb and make "didiscover" the discover there.

No change here. If the above problem is sufficiently solved, this and
the zlib integration can be next.

This is another vexing problem; Progeny still does not have public
anonymous CVS. It's my hope that this will be a reality sometime in the
