Permissions
-----------
Mock Turtle does not uses any special group or user on the host system;
all driver's files are owned by ``root:root``. Mock Turtle applications may
want to change this and assign special users, groups and permission. We suggest
to do this using ``udev(7)`` rules. To filter out a special application in
udev rules you should use the sysfs attribute ``application_id``. For example
the following rule matches the Mock Turtle device with application ID
``0xbadc0ffe``::
SUBSYSTEM=="mockturtle", KERNEL=="trtl-[0-9a-zA-Z][0-9a-zA-Z][0-9a-zA-Z][0-9a-zA-Z]", ATTR{application_id}="0xbadc0ffe"
