# This script (or its equivalent) has been installed non-executable for
# several dhcpcd releases leading me to believe this is intentional on the
# part of the developers. Indeed, the script is called a "sample" in the
# included comments, and there's been at least one security issue related
# to its use in the past, so it's probably a safer bet to not install it so
# that it works "out of the box". However, making it non-executable is not
# the best solution for this as it leads to error messages in the system
# logs which I hear about from time to time. Instead, we'll make it
# executable, but will give it a suffix of -sample so that dhcpcd won't
# attempt to run it unless the admin specifically configure it to do so.
# As far as I can tell it does nothing more than add some extra verbosity
# to the logs anyway, and rc.inet1 already does that. There's really no
# need that I can see to enable the script.
