初始化随机数种子
#! /bin/sh
#
# Preserve the random seed between reboots. See urandom(4).
#
# This script can be called multiple times during operation (e.g. with
# "reload" argument) to refresh the seed.
# The following arguments can be added to SEEDRNG_ARGS in
# /etc/default/seedrng:
# --seed-dir=/path/to/seed/directory
# Path to the directory where the seed and the lock files are stored.
# for optimal operation, this should be a persistent, writeable
# location. Default is /var/lib/seedrng
#
# --skip-credit
# Set this to true only if you do not want seed files to actually
# credit the RNG, for example if you plan to replicate this file
# system image and do not have the wherewithal to first delete the
# contents of /var/lib/seedrng.
#
# Example:
# SEEDRNG_ARGS="--seed-dir=/data/seedrng --skip-credit"

sysctl相关操作
#!/bin/sh
#
# This script is used by busybox and procps-ng.
#
# With procps-ng, the "--system" option of sysctl also enables "--ignore", so
# errors are not reported via syslog. Use the run_logger function to mimic the
# --system behavior, still reporting errors via syslog. Users not interested
# on error reports can add "-e" to SYSCTL_ARGS.
#
# busybox does not have a "--system" option neither reports errors via syslog,
# so the scripting provides a consistent behavior between the implementations.
# Testing the busybox sysctl exit code is fruitless, as at the moment, since
# its exit status is zero even if errors happen. Hopefully this will be fixed
# in a future busybox version.

#
# 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.
