| 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. |
