busybox: provide /etc/mdev.conf if mdev is used Without an mdev.conf file installed, mdev generates some /dev entries in an incorrect or non-standard way. Some examples: 1. /dev/null has permissions 660, but it should be accessible to normal users; 2. alsa devices get created in /dev, not /dev/snd as is more common, and as the default value of BR2_PACKAGE_ALSA_LIB_DEVDIR suggests; 3. event<N> files are created in /dev, not /dev/input. This mdev.conf is a selection from the examples provided in the busybox sources with minor tweaks.

# alsa sound devices
busybox: fix mdev.conf mdev does not set "/dev/snd" and "/dev/input" group and permission propery, because with commit c3cf1e30a3022453311a7e9fe11d94c7a381640e (May 2013!) the behavior of mdev has changed. The device name is now taken directly from the uevent file and does no longer match the old rule. Fix the rules for "/dev/snd" and "/dev/input" according to the example given in [1].

package/busybox: support automatic module loading with mdev A recently discussed on the mailing list: http://lists.busybox.net/pipermail/buildroot/2016-February/154189.html Our mdev configuration currently doesn't handle module loading. Fix that by: - Telling mdev to run modprobe on hotplug events providing MODALIAS - Adjust the init script to handle coldplug modalias events (E.G. modules for which the devices were already present before mdev was added as the hotplug handler). mdev -s should arguable handle this, but it doesn't.
