commit: http://git.buildroot.net/buildroot/commit/?id=937a95449ecaad02386523f8fe2eeefbea6be971
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/next
eudev is a userspace device management daemon. It is a standalone
version, independent from systemd. It is a fork maintained by Gentoo.
Features:
- No extra configuration options are available: Gudev is build if
libglib2 is selected.
- No dependency on hwdata as the package uses its own hardware
database (as does systemd).
eudev 1.3 is in sync with systemd v207.
[Peter: add BR2_USE_MMU dependency]

+#!/bin/sh
+#
+# 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.
+#
