eike-hotplug@sf-tec.de e64280b8b3 [PATCH] LSB init script and other stuff
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)
