Turning Off an AutoFS Map
To turn off an AutoFS map using the -null map, perform the following
steps:
1. Add a line with the following syntax to the AutoFS master map:
local_directory -null
2. If AutoFS is running, and you want to force it to reread its maps,
issue the following command on each client that will use the map:
/usr/sbin/automount
The -null option turns off the map that is mounted on
local_directory . For example, if the NIS auto_master map mounts
the auto_home map on /home, and you include the following line in your
local /etc/auto_master file, the auto_home NIS map is not used on your
system:
/home -null
The -null option is useful for turning off NIS AutoFS maps that do not
apply to your host.
You can also replace NIS maps with local maps; see the following
example from /etc/auto_master:
/home /etc/auto_ourhome
As AutoFS reads the local /etc/auto_master file before the
auto_master NIS map, this entry causes AutoFS to look for mount
information in the local file, /etc/auto_ourhome, instead of the
auto_home NIS map.
To use a local AutoFS master map, make sure the AUTOMOUNT_OPTIONS
variable in /etc/rc.config.d/nfsconf includes the -f $AUTO_MASTER
string. In addition, make sure the AUTO_MASTER variable is set to the
name of your local AutoFS master map file.
For more information, see the automount(1M) man page.
