Automounting Multiple Directories (Hierarchical Mounts)

If the map does not exist, create it, and add it to the AutoFS master map. Use an editor to create an entry with the following format in a direct or indirect map:

local_dir   /local_subdirectory [-options] \ server:remote_directory \
/local_subdirectory [-options] server:remote_directory 

The backslash (\) characters instruct AutoFS to ignore the line breaks. This entry is effectively all one line.

With this format, map entries cause the listed remote directories to be mounted only when referenced. For example, the following entry from a direct map mounts the source code and the data files for a project whenever anyone requests access to both of them:

/our_project   /source   -ro    broccoli:/opt/proj1/src  \
               /datafiles    cauliflower:/opt/proj1/samples/data

The following is another example from an indirect map.

chap2 -nosuid   /text       sage:/our_book/chap2  \
                /graphics   basil:/our_book/artwork/chap2 \
                 /old         sage:/our_book/oldfiles/chap2
 
The same mount option (nosuid) applies to all three automounted directories.
