ldd /bin/udevadm ... libidn.so.11 => not found ... Reproducible: Always
I also ran into this problem. In my case it resulted into a semi-unbootable system, presumably because I have /usr on a separate partition. I had to login on the console, manually start udev and udev-trigger and then revert to sys-fs/udev-233.

Officially, we only support such a configuration if /usr is mounted early by an initramfs. It may otherwise work by accident, but don't count on it.
