Normally the kernel connects /dev/console and the init-process.
But only if /dev/console (or $CONSOLE) exists on the root-partition.
If it does not fds 0, 1 and 2 are closed.
In that case I have to add
# exec 0<> $CONSOLE 1>&0 2>&
to every init-script?
And for that even create $CONSOLE before executing udev, as that does not 
exist in empty tmpfs.

For all other init-scripts/daemons it works without, but not for udev.
If this bug is solved we still can boot from a partition with completely 
destroyed/cleaned /dev, without crashing bootup at udevd startup.
