Thanks for the update. I'm afraid I haven't been paying close attention,
but a cursory search didn't uncover any description of what I'm supposed
to do with a .udeb that includes a shared library in our glorious
Multi-Arch world of the future.

I'm assuming that any files destined for /usr/lib should land in the
architecture-specific sub-directory, right?

The convention I've adopted so far for udeb-building packages has been to
install libraries in /usr/lib instead of to /usr/lib/$arch. While
/usr/lib/$arch is perfectly findable by ld.so in the installer environment,
and while any plugins still need to be installed to the multiarch path if
you're doing a single build of the source for both .deb and .udeb, I think
it just adds unneeded complexity to use /usr/lib/$arch for shared libraries
in udebs.

Since this is the third time this question has come up, I guess that makes
it a FAQ; added now at
<http://wiki.debian.org/Multiarch/Implementation#udeb_handling>.

BTW, if the package you're asking after happens to be fontconfig, I have a
patch here that I'll be sending on shortly. :-)

Ok, that makes sense to me. Of course, it's also harder for me to manage
in the package as I'm installing the same library in the .udeb as I do
in the library .deb file. I'll manage.

Oddly, it is (the only package I have with a .udeb). I'm running a
multi-arch version of that on this machine and it appears to work
correctly. You can see this at:

git://git.debian.org/git/pkg-freedesktop/fontconfig-debian

Yep, looks almost identical to my patch here, with only one difference: the
runtime support packages need to be marked Multi-Arch: foreign in order to
satisfy the dependencies of the multiarch libraries. Attached. (This is
also bug #614208.)

Then I guess I should mark that as closed then. I've pushed updated
packaging bits; I wouldn't mind if you'd check and make sure they look
right before I upload the resulting package.

Looks perfect, thanks!
