to reproduce the problem I met, simply add to a conf file :
PREFERRED_VERSION_udev = "164"

and using oe-core + meta-oe try to build anything which has "inherit
systemd" (even if in the end you don't install the corresponding
${PN}-systemd in the target's rootfs) : systemd's configure will fail
because it requires a more recent udev.
