# During an upgrade this class action script merges user modifications in
# the original ($dest) /etc/default/rpc.nisd into the new replacement
# /etc/default/rpc.nisd ($src) file.
#
# If there is no existing default/rpc.nisd file, the script simply copies
# the new default/rpc.nisd file into place. However, if there is an
# existing default/rpc.nisd file, the script greps out each line which sets
# a parameter in the original file and overwrites the corresponding line in
# the new default/rpc.nisd file.
#
# The script works by looping through each variable name, grepping out the
# apropos line, and creating a sed line, which when applied to the
# replacement default/rpc.nisd file will preserve modifications in the
# original default/rpc.nisd file.
