        <pre>A switch like --root or --installroot is required. The thing is that we call
`udevadm hwdb --update` at the end of udev installation, in the post install
phase in 2 places: udev and hwids package that contains all the iab.txt,
oui.txt, pci.ids, and so forth

The postinst phase must be called with ${ROOT} as the package manager is
supposed to support ${ROOT}. So the files should be picked up from ${ROOT} what
it uses to generate the hwdb.bin and the hwdb.bin should also end up in the
actual ${ROOT}

udevadm hwdb --update --root="${ROOT}"

And if not defined, ${ROOT} is just /

Currently this is breaking the packaging of udev for Gentoo, in fact, this is
the only real problem we are having.

Thanks for looking into it</pre>
