    55Stackable VFS (Virtual File System) modules support was new to Samba-3 and has proven quite popular. Samba
    66passes each request to access the UNIX file system through the loaded VFS modules. This chapter covers the
    77modules that come with the Samba source and provides references to some external modules.

    1111If not supplied with your platform distribution binary Samba package, you may have problems compiling these
    1212modules, as shared libraries are compiled and linked in different ways on different systems. They currently
    1313have been tested against GNU/Linux and IRIX.

    18 To use the VFS modules, create a share similar to the one below. The important parameter is the <a class="indexterm" name="id408857"></a>vfs objects parameter where you can list one or more VFS modules by name. For example, to log all
    19 access to files and put deleted files in a recycle bin, see <a href="VFS.html#vfsrecyc" title="Example 23.1. smb.conf with VFS modules">the smb.conf with VFS

    2525The modules are used in the order in which they are specified.  Let's say that you want to both have a virus
    2626scanner module and a recycle bin module. It is wise to put the virus scanner module as the first one so that
    2727it is the first to get run and may detect a virus immediately, before any action is performed on that file.

    4949        This module allows the default quota values, in the windows explorer GUI, to be stored on a Samba-3 server.
    5050        The challenge is that linux filesystems only store quotas for users and groups, but no default quotas.
