3# udev This is a minimal non-LSB version of a UDEV startup script. It
4# was derived by stripping down the udev-058 LSB version for use
5# with buildroot on embedded hardware using Linux 2.6.34+ kernels.
6#
7# You may need to customize this for your system's resource limits
8# (including startup time!) and administration. For example, if
9# your early userspace has a custom initramfs or initrd you might
10# need /dev much earlier; or without hotpluggable busses (like USB,
11# PCMCIA, MMC/SD, and so on) your /dev might be static after boot.
12#
13# This script assumes your system boots right into the eventual root
14# filesystem, and that init runs this udev script before any programs
15# needing more device nodes than the bare-bones set -- /dev/console,
16# /dev/zero, /dev/null -- that's needed to boot and run this script.
