It was /run/udev/firmware-missing/*, udev cannot access /var.

All of that is gone and will not come back, udev has no idea about
device firmware and does no longer want to know about it. There is no
way to tell these days what firmware was requested or loaded, it's all
happening in the kernel only.

Unless we want to invent a mechanism to queue up/log that information
in the kernel and communicate that to userspace, you can just delete
all the code that handles this in userspace.
