Autofs Configuration Files

These are the configuration files needed in /etc/ in order for users' home directories to get mounted on a client. Some of these files may not be necessary! This should be researched. At the very least, auto.master and auto.net are needed.

auto.master

# $Id: auto.master,v 1.4 2005/01/04 14:36:54 raven Exp $
#
# Sample auto.master file
# This is an automounter map and it has the following format
# key [ -mount-options-separated-by-comma ] location
# For details of the format look at autofs(5).
#
#/misc	/etc/auto.misc
#/net	-hosts
#
# Include central master map if it can be found using
# nsswitch sources.
#
# Note that if there are entries for /net or /misc (as
# above) in the included master map any keys that are the
# same will not be seen as the first read key seen takes
# precedence.
#
#+auto.master
#
# This is *not* the default /etc/auto.net
/net	/etc/auto.net

auto.net

# This script overrides the default distribution-provided /etc/auto.net,
# retaining support for our custom namespaces while still allowing the
# wildcard functionality.  E.g. /net/data/taro and /net/taro/data are
# interchangable.  Paths such as /net/data/wheel and /net/www/physics
# are still preferred over explicit paths as the host providing such
# services may change at a future date.
