# Paths to skeleton port's source & real Slackware source tree:

# Temporary build locations:
export TMPBUILD=$TMP/build-$PACKAGE
export PKG=$TMP/package-$PACKAGE

# Determine the CFLAGS for the known architectures:

# This changes the default location where the .pid and
# other files are written from /var/run to /etc/dhcpc.
# The latter directory was long traditional, and (more
# importantly) you can't be sure that /var is mounted
# yet when dhcpcd is invoked.

# This script 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.
#
# 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.

  else

# Perform any final checks on the package:
