Configuring and Administering AutoFS
Creating a Hierarchy of AutoFS Maps
Chapter 3140
Beginning with the AutoFS mount at /org, the evaluation of this path
dynamically creates additional AutoFS mounts at /org/eng and
/org/eng/projects. On the user’s system, no action is required for the
changes to take effect, because the AutoFS mounts are created only
when required. You need to run the automount command only when you
make changes to the master map or to a direct map.
