# 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.
