Package: libiio0 Version: 0.25-1 Severity: important Tags: patch User: helm...@debian.org Usertags: dep17p7 X-Debbugs-Cc: helm...@debian.org
Dear Maintainer, libiio0 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 [1] https://wiki.debian.org/UsrMerge
