Create menu entry to select device creation method Four methods for the creation of device files in /dev are now proposed: - static method uses device table as before - devtmpfs method enables this feature in kernel - mdev method adds mdev starting script to the file system and selects mdev itself for installation - udev method selects udev for installation All dynamic methods are based on devtmpfs, so one doesn't need to care about /dev folder.

busybox: register mdev as hotplug helper when selected It's also done in the kernel configuration, however users may be using some other pre-built kernel and miss functionality like firmware loading.

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.

package/busybox: support spaces in module aliases in mdev The new change which enabled automatic module loading on boot does not handle the cases when module alias includes spaces. It prevents modules to be loaded since script fails: % find /sys/ -name modalias \| xargs sort -u sort: /sys/devices/platform/Fixed: No such file or directory First alias in question is "platform:Fixed MDIO bus". Amend the script to support above like cases.
