@gasinvein any clue what's going on here? Are we writing hwdb into wrong place?

Looks to me like the path comes from here https://github.com/eudev-project/eudev/blob/master/configure.ac#L175C27-L175C38

This looks to me like a bug in hwdb? Expected path is /app/etc/udev/hwdb.bin after string combining operations.

I think we might be able to trick it to write to right place by using --usr which in our case writes to /app.
