Enhanced AutoFS Administrator's Guide, September 2005

Configuring and Administering AutoFS
Using the Features
Chapter 3 23
# /etc/auto_indirect file
# local mount point mount options remote server:directory
/test -nosuid thyme:/export/project/test
/apps -nosuid basil:/export/apps
Considering that you have the preceding AutoFS master and indirect
maps on the NFS client, sage, issue the following commands:
cd /nfs/desktop
ls
The output of the last command (ls) is as follows:
test apps
The ls command displays this output because the test and apps
subdirectories are the potential mount points (browsability), but are not
mounted currently. However, if you issue the following commands, both
the test and apps subdirectories are mounted.
cd /nfs/desktop/test
cd /nfs/desktop/apps
NFS Loopback Mount
By default, AutoFS uses LOFS mounts for locally mounted file systems.
Enhanced AutoFS provides an option to enable loopback NFS mounts for
the local mount.
You can use the automountd command with the -L option to enable the
loopback NFS mounts for locally mounted file systems. You need to use
this option in the High Availability NFS environments.
