I ported the rc.autofs script (from the autofs userspace tools package)
to Slackware 9.1. Is it of any use to you?

# rc file for automount using a Sun-style "master map".
# We first look for a local /etc/auto.master, then a YP
# map with that name
#
# On most distributions, this file should be called:
# /etc/rc.d/init.d/autofs or /etc/init.d/autofs
#
# For Redhat-ish systems
#
# chkconfig: 345 15 85

# location for the S- and K-links to this init file.
# The following value is extracted by debstd to figure out how to
# generate the postinst script. Edit the field to change the way the
# script is registered through update-rc.d (see the manpage for
# update-rc.d!)
