Heh, I'm 'unfortunately' obliged to include meta-oe even if I want to build
a core-image-minimal for the machines in meta-handheld.

The problem is there are two sets of udev recipes! There should be one,
only one layer containing core packages.

I understand this is problematic and that Angstrom is already testing
systemd, still we should focus and find a concrete proposal for merging
with oe-core asap!
