Hi,

libvpd-2.2-3 contains a udev .rules file and installs it using
debhelper. In the bookworm build (+b1), it was installed to
/lib/udev/rules.d whereas in a later rebuild for trixie (+b2) it was
installed to /usr/lib/udev/rules.d due to the /usr-move (DEP17). As it
also is marked M-A:same, this file may be lost in upgrade scenarios from
bookworm (+b1) to trixie (+b2). For more information refer to
https://subdivi.de/~helmut/dep17.html sections P7 and M10 in particular.
I propose mitigating this problem by adding protective diversions for
the duration of the upgrade. Those diversions are no longer present once
the upgrade is completed. As a result, the changes can be fully reverted
once trixie is released. I am attaching a patch for your convenience. It
has marked all removable sections in such a way that the Debian janitor
(operated by Jelmer) can automatically file a merge request to perform
this deletion. I tested this patch by performing a cross build for
ppc64el and upgraded the package in a qemu-user environment. I
appreciate if you could do more testing on real hardware ahead of
upload. Let me know if you have any questions.

Hi Adrian,

it appears that Frédéric Bonnard is not really active anymore.
I've CCed you as PPC porter. Maybe you can have a look at this bug
report and do an NMU / take over the package.

Regards,
Michael

Hi,

It didn't. There were just a few other things that kept me busy last
week, including a smartphone that nearly got lost when I sent it to
repair.

I'll look at it either today or tomorrow.

Thanks,
Adrian

With the freeze in effect, it has probably become a bit harder to get
ppc64-diag and libvpd back into trixie.

https://tracker.debian.org/pkg/libvpd


That said, I have no idea how important those packages are for ppc(64)
or not (and if removal of those packages is a valid option as well).

As it stands today, those packages will not be part of trixie.
I've added debian-powerpc to CC to gather further feedback
