My understanding is that the problem isn't with the location of libraries - it's with the location of data under /usr/share. Stuff like the pci.ids and usb.ids files, which are apparently required for some of the udev rules. Those files could presumably be moved to somewhere under /, but there's no obvious place to put them, no /share directory... Simonl
