Ross,

yeah, you were right - I mistook the existing libudev and udev rpms not to be from systemd before I checked the contents (they DO contain only udevstuff "generated" by systemd). So the image build itself was ok all the time, but libudev.so.0 just doesn't exist when using systemd.

However, about my actual problem: I managed to package Google Chrome successfully by adding SKIP_FILEDEPS_${PN} = "1" and by creating a symlink /opt/google/chrome/libudev.so.0 -> ../../../lib/libudev.so.1 in do_install. A bit dirty, but this is what the official deb from Google seems to do to manage the different versions. Also skipping file deps inspection is not clearly an optimal solution, but works for me in this case.

Thanks for your help, 

Timo
