Hi,

Thanks for reporting. I think this has been missed for a long time, the
blame line for version 196 claims it's 11 years old...
usbutils seem to use it for the hwdb implementation.

This hasn't triggered because I think most targets are systemd based.
And that hwdb implementation should work fine. I have locally been
running eudev instead of udev as a drop in replacement for ages. And
that one works fine too.

I think the correct solution here is to use eudev (which is actively
developed still) and drop udev-182 (12 something years old by now?) or
just drop legacy builds without systemd altogether.

I'm not really a fan of the latter, but the argument against it
increases as time passes by.

I could post the eudev drop in replacement bump (probably needs some
more work), but I'm unsure if people in general thinks it's worth the
hassle.

Regards,
Christian

I think it should also be possible to just install the new udev from the
current systemd sources without systemd itself. But such an update needs to
be done by someone who actually uses that. For many years now I've only had
projects that use systemd.
