Fiona Klute 41258a8194 package/eudev: refactor init script and rename it to S10udevd
This brings the script in line with current init script standards, and
fixes all make check-package warnings. Other notable changes:

* Use start-stop-daemon to create a PID file, so we can monitor shutdown.

* Use "udevadm control --exit" to implement stop, instead of "killall".

* Do not require /etc/udev/udev.conf to exist, the default contains
  only comments and udevd works without.

* Do not parse /etc/udev/udev.conf, the udev_root configuration option
  it was used for has been removed in version 1.5.1 [1].

* Implement reload using udevadm.

# udev This is a minimal non-LSB version of a UDEV startup script. It
# was derived by stripping down the udev-058 LSB version for use
# with buildroot on embedded hardware using Linux 2.6.34+ kernels.
#
# You may need to customize this for your system's resource limits
# (including startup time!) and administration. For example, if
# your early userspace has a custom initramfs or initrd you might
# need /dev much earlier; or without hotpluggable busses (like USB,
# PCMCIA, MMC/SD, and so on) your /dev might be static after boot.
#
# This script assumes your system boots right into the eventual root
# filesystem, and that init runs this udev script before any programs
# needing more device nodes than the bare-bones set -- /dev/console,
# /dev/zero, /dev/null -- that's needed to boot and run this script.
