# This is a script for replacing udev binary during udevsend/udevd testing.
# It just simply logs the event information sent by udved in order to
# test script udevd-test.pl can analyze whether udved execute as we expected.
# You should not execute this script directly because it will be invoked by
# udevd automatically.
#
# Before you run your test please modify $log_file to designate where the udev
# log file should be placed, in fact, the default value is ok.
