Jérémy, All,

udevadm was not in your previous iteration, but now it is.

This means that, when BR2_PACKAGE_SYSTEMD_HWDB=y, we now have two host
packages that provide udevadm: host-systemd and host-eudev.

We can't keep both.

So, I would change BR2_PACKAGE_SYSTEMD_HWDB to drop the select to host
eudev now; we don't need it anymore. If systemd is enabled, then
host-systemd will always be built, so we will always have a udevadm.

Yann E. MORIN.
