The firmware-sof-signed 2024.06 package:
https://packages.debian.org/trixie/firmware-sof-signed

In particular the sof-ipc4-tplg package that is being converted from a directory to a symlink. The dpkg-maintscript-helper complains about /usr/lib/firmware/intel/ sof-ace-tplg (and it's contents) not being owned by the package - because they were all previously under /lib.

I suspect this is more of a special case, so would like to see a few
more details.

Holler if you need anything else.

I test upgraded firmware-sof-signed from bookworm to trixie. The bookworm chroot was usrmerged.

Ok, I see the problem now.



The attached debdiff should do.

The issue is, that the path used in dir_to_symlink changed pre and post usrmove. I don't think you can express that via a .maintscript file.
