- # 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.
- #
- # Check for config file and read it
