Dear Maintainer,

your package installs files related to udev, into /lib. These
files need to be moved to /usr/lib as part of Debian's usr-merge
effort [1].

Attached you will find a patch using udev.pc to place the udev files
(using pkg-config). This works today in unstable and also for
bookworm, and is safe to do now.
Once udev.pc in unstable points to /usr/lib, your package will
benefit automatically after a binNMU or any other upload.

If during the trixie cycle your package will undergo structural
changes or any other file moves, please see the wiki and upload
to experimental first when these changes are done.

Later during the trixie cycle I expect this bug class to raise in
priority.

Thank you for considering,
Chris
