Configuring AutoFS Using the/etc/default/autofs File
You can also use the /etc/default/autofs file to configure your AutoFS
environment. The /etc/default/autofs file contains parameters for the
automountd daemon and the automount command.
Initially, the parameters in the /etc/default/autofs file are commented. You must
uncomment the parameter to make the value for that parameter take effect. Changes
made to the /etc/default/autofs file can be overridden if you modify the AutoFS
values from the command line.
When AutoFS starts up, and if the AUTOMOUNT_OPTIONS variable specifies a master
map file with the -f filename option, AutoFS searches for a file by that name on the
local host. It can also use the Name Service Switch (NSS) to determine which name
services are in use. In addition, it determines the master maps that are available from
those name services.
If the AUTOMOUNT_OPTIONS variable does not specify the -f filename option,
AutoFS consults the NSS configuration, to determine where to search for the AutoFS
master map.
For more information on configuring the NSS, see nsswitch.conf (4) and automount(1M)
.
To configure AutoFS using the /etc/default/autofs file, follow these steps:
1. Log in as superuser.
2. Edit the /etc/default/autofs file. For instance, to change the default time for
which a filesystem remains mounted when not in use, modify the
AUTOMOUNT_TIMEOUT variable, as follows:
AUTOMOUNT_TIMEOUT=720
For the list of parameters supported in the /etc/default/autofs file, see
autofs(1M).
NOTE: Values modified using the /etc/default/autofs file are updated when
the command or daemon is started. This update is made irrespective of the way the
command or daemon is started, Autofs startup script or command-line.
Enabling AutoFS
To enable AutoFS, follow these steps:
1. In the /etc/rc.config.d/nfsconf file, set the value of AUTOFS variables to
1, as follows:
AUTOFS=1
2. Configure AutoFS using either the /etc/rc.config.d/nfsconf or the /etc/
default/autofs configuration files. If you use a local file as the master map,
