Package: libxtrxl0
Version: 0.0.1+git20201202.1b6eddf-1
Severity: important

Dear Maintainer,
libxtrxl0 contains udev files which are installed to /lib; these files
need to be moved to /usr/lib as part of Debian's usr-merge effort.
Because your package is Multi-Arch: same, an unfortunate corner-case can
occur whereby shared files (such as the udev rules) may be erroneously
removed on upgrades (please see DEP17[1] P7: Shared multiarch file
loss).
You will find a patch attached to move the udev files, including the
mitigation for the file loss scenario.
Please consider applying this patch at your earliest convenience. This
bug will be upgraded to release critical soon, as it blocks the overall
usr-merge effort which is being undertaken for the trixie release.
Many thanks,
Chris
