Jonathan Liu 29afecace9 udev: process udev events on startup in init.d script
udev rules are not processed for kernel events that occur before
the udev daemon is started. Call udevadm trigger to replay these
missed events.

# 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.
