It's hard to speak for "everyone", but I
am not. Contributions welcome.
To summarize my understanding of the issue (which
is easily the wrong understanding) is that p2 introduced this new IU filter
(macosx-bundled) that should be "transparent" to everyone; that
we (in Platform, and Sim. Release repo) do not want this "phantom
IU filter"; we have no plans to support or provide it; and most important,
I do not know how to "get rid if it". (There's some vague suggestion
that "every time a repo is mirrored it has to be filtered out"
... but I don't really know what that means or why we should have to if
"transparent" to everyone.)
You don't say ... are you trying to make use of the
"macosx-bundled" filter? Or the legacy layout? If the former,
I think you can't ... if the latter, you may be able to refine your filter
Again, contributions welcome, and bug 407588 is likely
best place to discuss the issues.
