Very Important!!!!! Also update x11-server too!
It's actually really lucky the path to udevadm changed as I'd have
otherwise been super confused! It turns out correcting this problem
highlighted another - an infinite trigger loop in udev.
The rules file:
/etc/udev/rules.d/61-x11-input.rules
calls /sbin/mageia-setup-keyboard.
mageia-setup-keyboard in turn uses the variable UDEV_LOG to work out if
we're called within udev or not. If not it assumes it's being run
"standalone" rather than via udev.
I've fixed this looping now and it should be backwards compatible with
the current udev.
So make sure you update the x11-server at the same time otherwise you
might have a hard time until you reboot.
If you do get stuck, just rm /sbin/udevadm symlink in rescue.target (aka
runlevel 1). udevd will be happily going quite nuts until you reboot :)
