[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)
