Filemounts limit a user to just a specific folder tree under the
fileadmin directory. This is good for security purposes, as well as general usability in a multiuser environment. Instead of browsing through all the files available in the system, the user can be directed to just the files he/she needs to manipulate.
To set up filemounts, you must have a directory structure in place. For the recipe that follows, we will assume that we decided on a "by user" tree (see recipe Setting up file structure).
