So, administrivia aside, the substantive reply. But first:
I'm going to ride herd on this thread when it comes to respect. We can
disagree without making comments about "amateurs" and "misguided" and so on.
In particular, this idea that somehow these decisions are the result of
anti-inclusiveness or collusion or some such are really offensive. I
wouldn't have called this conversation to the list if I wasn't really
interested in your input.
Mis-communication happens. You can treat it as evidence of malice, or
just a mistake. If you choose the former, good luck to you. If you
choose the latter, then the fix is to communicate; let's do that, OK?

That (the modification attack) sounds like something that should be

Way back when, I kept saying that Debian packages were superior to RPMs,
and now I have my confirmation. :-)
I joke, but really, the evidence suggests that RPM was, in fact, very
useful even in its version 3 configuration. I remember switching from
Slackware to Red Hat 3 way back when precisely because of the advantages
Given that usefulness, I don't see why the better must be the enemy of

In our bug evaluation, we didn't get to 1875, but I see from Ted's
spreadsheet that the bug got an average rating of 2.2 on a 5-point scale
(lower numbers being higher priority). That would probably put the bug
on the same priority as the uplift, as things stand now.
That would suggest that, should the uplift take higher priority, the bug
should probably rise with it.

OK. BTW, I've added some links here:
All are welcome to expand on those, add further information, etc.

I don't think this is exactly what Ted was talking about, but OK. The
positive plan is sensible.

I note that not a single distro has weighed in on that bug.
That's probably why the fix hasn't been pushed: we don't have the
authority to make calls like that.

Well, we're always happy to take code that's already done. OTOH, I
don't know that we're in a position to take all of RPM 5 into the SDK,
so the tool's deps on RPM 5 will have to be looked at.

Maybe they're all lazy bums. Is telling them so going to get us
anywhere? We have to deal with the world we live in, and not the world
Sometimes giving people what they want--while, at the same time,
encouraging them down a certain path--gets you farther. That's what
we're trying to do.

Sure. But it's still got to be done, unless you know of a good way to
access those lessons from alien without having to rewrite them.

Well, sure. That was, in fact, a large part of the conversation we had
at the Summit, and has been a theme of many of our conversations with
lots of ISVs.
It is, in fact, a motivator for a lot of what we want to do in LSB 4.

Frank talk is welcome; disrespect is not.
We took this off the call precisely because, with the strong opinions
represented and the time allowed, we weren't going to do anything
productive about it then. I hope we can do something productive about
it now, in an environment where we can be a little more cool-headed and
explain ourselves well.
