#
# This is a script for replacing udev binary during udevsend/udevd testing.
# It first amplifies the execution time ( sleep 5 ) and then logs the event
# information sent by udved in order that 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.
