UbuntuHelp:Autofs

Introduction
Automount is the modern way to mount directories over a network. It is much easier to manage and more economic in bandwidth than static mounts via fstab. In this howto, installation and configuration of a files based configuration autofs will be presented. It is not used a lot anymore, but AutofsLDAP is very useful and based on this one. In small business environment, this howto can be useful (why?)[because one could expect some servers and shares/exports that have to be distributed using autofs (preferably via yp).
Installation
Install the following packages: autofs (see InstallingSoftware)
Configuration
For configuring autofs, you have to edit /etc/default/auto.master file. Here is the sample file provided by Ubuntu:
# # $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 --timeout=60 #/smb /etc/auto.smb #/misc /etc/auto.misc #/net /etc/auto.net
As you see, by default, all is commented out. Each mount point is associated with another configuration file. Most of them are now useless (now modern desktop have automount feature with hal & co). This would be useful for light desktop. /net and /smb are still useful.
In Unix world, /net enable automounting distant file system exported by NFS. For example, if you have a server named fileserver with a NFS export directory called /export (see NFSServerHowTo for how to setup a such server), you can mount it by typing in a shell command line cd /net/fileserver/export. In an environment with NFS file servers, such automount can be useful.
For /smb mount point, function the same way but is for SMB file systems (if you need to authenticate for acceding the SMB share, the automatic way will not function).
Uncommenting /net and /smb is a good solution.
You can add your own mount point with your own options in /etc/auto.master to suit your needs.
After entering your changes, run the following command to have them taken into account:
sudo /etc/init.d/autofs reload
In other documentation Autofs and Automount seem to be used interchangeably however this document seems to indicate they are different. This document, about Autofs, starts by talking about Automount and then indicates that Autofs is "not used a lot anymore" even though AutofsLDAP is useful. If Automount is an alternative to Autofs, where is the documentation on Automount? SettingUpNFSHowTo still refers to autofs for mounting nfs shares automatically and frankly explains the use of autofs better. This document needs rewording to make it more clear.
