This should fix one of the more annoying things to me about udev, and gets rid of a TODO item.

# udev-test
|
|
#
|
|
# Provides automated testing of the udev binary.
|
|
# The whole test is self contained in this file, except the matching sysfs tree.
|
|
# Simply extend the @tests array, to add a new test variant.
|
|
#
|
|
# Every test is driven by its own temporary config file.
|
|
# This program prepares the environment, creates the config and calls udev.
|
|
#
|
|
# udev reads the config, looks at the provided sysfs and
|
|
# first creates and then removes the device node.
|
|
# After creation and removal the result is checked against the
|
|
# expected value and the result is printed.
|
|
#
|
|
# happy testing,
|
