init.d/udev

[Benoit Valiron]

Again about udev, I noticed that init.d/udev consider udev devices
installed in /udev. In particular, the script set udev_root just
after parsing /etc/udev/udev.conf, in which this variable is already
defined (in my case, as "/dev") :

----- quote from init.d/udev ---------------
. /etc/udev/udev.conf

prog=udev
sysfs_dir=/sys
bin=/sbin/udev
udevd=/sbin/udevd
udev_root=/udev
----- end of quote ------------------------

This causes problem during the creation of stdout, stdin and stderr,
which are then created in /udev instead of /dev.


I noticed on my box another problem, but maybe it's just me. When
halting the system, udev complains that "/dev/null" is missing.

I solved the problem with an horrible hack (please do not kill me yet,
I know, it's awful), by asking the script not to delete /dev/null in
the loop which remove each device.

I told you, it's awful.
