Upon inserting a USB stick or similar device, mdev will run
an automounter script that mounts valid partitions on
/media/<device>. The script first checks /etc/fstab entries
so that mounting on UUID or LABEL or using custom mount options
is still possible. If /etc/fstab does not contain particular
mount options, the script will create (and remove) the mountpoint
automatically.
The script also supports full disk partitions (devices without
partition table).
The following environments can be set in /etc/default/mdev:
MDEV_AUTOMOUNT=n (Disables automounting completely)
MDEV_AUTOMOUNT_ROOT=/media (Change the mount root location)
Automatic mounting for a particular device can be disabled by
creating a file "/dev/<device>.nomount". This is helpful in
scripts that create partitions for example, and want to perform
specific actions which require the device to remain unmounted.
A more complex variation (using LABEL based mounts) on this script
has been in use in OpenPLi for many years now, and I've used this
one on many projects already, so it's about time to push this to
mainline.

Add a line to mdev.conf that tells mdev to load kernel modules when
required.
For example, if you built wifi support as an external module, inserting
a wifi stick into a USB port will now automatically load that module
into the kernel and the wlan device will be ready for configuration.
Without this patch, you have to load required modules manually or force
them to load at system startup.

busybox 1.21.1 's mdev has changed the way the device's name is
reported so now we get input/event0 instead of event0.
I think this commit is responsible of this new behaviour :
http://git.busybox.net/busybox/commit/util-linux/mdev.c?id=c3cf1e30a3022453311a7e9fe11d94c7a381640e
Update mdev.conf according to this behaviour so that sound
and input devices are correctly populated (and now
/etc/mdev/find-touchscreen.sh is executed).
Tested on an arm board.

This changes the packaging only if the configuration used has mdev
support enabled.
