after implementation of https://wiki.debian.org/UsrMerge
firmware packages in trixie contain /usr/lib/firmware
in the paths (instead of /lib/firmware in bookworm).

compare:
https://packages.debian.org/bookworm-backports/all/firmware-iwlwifi/filelist
/lib/firmware/intel/ibt-0040-0041.ddc
...

and:
https://packages.debian.org/trixie/all/firmware-iwlwifi/filelist
/usr/lib/firmware/intel/ibt-0040-0041.ddc
...

therefore, the list_deb_firmware() function from check-missing-firmware.sh
does not find files in new packages.

the simplest solution is to ignore the "/usr" in the file paths
(the patch is attached).

Hello Andrew,

    @Andrew: Which version of live-build are you using? (lb --version)
We still use the version 20240810. We upgraded it from the bookworm version and it has been working fine till latest Trixie's changes (we build a custom ISO based on the mostly Bookworm packages + Trixie's kernel + debian-installer + some more not important updates).
The live-build package is tested with sid, testing, stable and oldstable, so you should be fine to use bookworm with trixie mixed in. 

You can even use the git version.
I've checked the code and see it contains the "Firmware_List_From_Contents" function but a simpler version.
It was fixed in git some time ago. The version from trixie is sufficiently new.
We will upgrade it after some tests. Right now we applied the attached patch and it works (but slow, of course).
Thank you all, guys. Now i see that we should use the latest live-build version (however, it might not work with bookworm packages, not sure right now).
Ok, I'm closing this bug report. If you have issues with the current live-build, please file a bug report against that package. 

With kind regards,
Roland Clobus
