+#
+# 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 2.6.12+ 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.
