I had too much time during the holidays, so I played a bit with udev. The changes are like last time mostly on the init stuff. I'm sending you this as a great diff which is just for comments. What it does: -fix a typo in Makefile -use only one "grep -v" instead of many -don't include BK-Files into release (shrinks the stuff to 30%!) -add a new init script which is LSB compliant -add some flags to choose which one to use -use /etc/udev/udev.conf in Redhat init script as the source for the udev directory. If this is not done then the init script may create a directory which udev itself isn't using (I changed /udev to /Udev to avoid collisions with /usr and ran into this) -first check for sysfs_dir before creating udev_root (maybe someone else has already fixed this, I saw this discussion on lkml)

# Short-Description: manage user-space device nodes in /udev
|
|
# Description: Start udev to create the device files for all
|
|
# devices already present in system when script is
|
|
# called. All other devices files will be automatically
|
|
# created when udev is called via /sbin/hotplug.
|
|
# Requires at least a kernel 2.6 to work properly.
