This would need systemd-hwe to be promoted to main in jammy as well. Let me actually do that now.

The src:systemd-hwe package contains a test script[2] to ensure that no redundant hwdb rules are added to the package, i.e. rules that are already present in src:systemd. This test requires patches to implement --root flag support for the `systemd- hwdb query` command[3]. These patches are already present in kinetic. Without these patches in Jammy, src:systemd-hwe would have to disable these tests, which are important to maintaining HWE hwdb rules in Ubuntu. [1] https://bugs.launchpad.net/ubuntu/+source/systemd-hwe/+bug/1983996 [2] https://git.launchpad.net/~canonical-foundations/+git/systemd-hwe/tree/tests/hwdb-redundancy?h=main [3] https://github.com/systemd/systemd/pull/23518 [Test plan] * Create a new directory for testing hwdb rule queries: $ mkdir -p fakeroot/etc/udev/hdwb.d * Add a new .hwdb file to override an existing rule. For example, I chose to override the last entry from /lib/udev/hdwb.d/60-keyboard.hwdb: $ tail -2 /lib/udev/hwdb.d/60-keyboard.hwdb > fakeroot/etc/udev/hwdb.d/60-keyboard.hwdb $ sed -i 's/chromebook/reserved/g' fakeroot/etc/udev/hwdb.d/60-keyboard.hwdb $ cat fakeroot/etc/udev/hwdb.d/60-keyboard.hwdb evdev:atkbd:dmi:bvn*:bvr*:bd*:svnAcer*:pnPeppy:* XKB_FIXED_MODEL=reserved * Create the hwdb.bin within fakeroot: $ systemd-hwdb update --root fakeroot $ ls fakeroot/etc/udev/hwdb.bin fakeroot/etc/udev/hwdb.bin * Finally, attempt to query this new hwdb.bin using systemd-hwdb query. On an unpatched system, we will see results from the system's hwdb.bin: $ systemd-hwdb query --root fakeroot evdev:atkbd:dmi:bvn*:bvr*:bd*:svnAcer*:pnPeppy:* | grep XKB_FIXED_MODEL XKB_FIXED_MODEL=chromebook ...and on a patched system we should see the overridden rule: $ systemd-hwdb query --root fakeroot evdev:atkbd:dmi:bvn*:bvr*:bd*:svnAcer*:pnPeppy:* | grep XKB_FIXED_MODEL XKB_FIXED_MODEL=reserved [Where problems could occur] The patches add support for the --root flag when calling systemd-hwdb query, thus changing the behavior of this command (previously, query would always load the system's hwdb.bin). It is unlikely that existing scripts try to use the --root flag with `systemd-hwdb query`, but if they did, this is where we would see problems.
