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.

busybox: S01mdev: fix module autoloading Commit b4fc5a180c (package/busybox: support spaces in module aliases in mdev) changed the mdev coldplugging to handle sysfs path elements and modalias values containing spaces. This unfortunately doesn't work as was recently reported: http://lists.busybox.net/pipermail/buildroot/2018-May/220903.html The problem is that sort -z also expects the fields of the input files to be zero terminated, which is not the case for modalias sysfs entries. So drop the -z option to sort. Spaces in modalias entries could be handled with the xargs -d '\n' option, but that is unfortunately not supported by the busybox applet. Instead, use tr to convert newlines to zeros so we can use xargs -0.
