+<varlistentry><term>AUTO-CREATE-SLOT</term><listitem>

+<varlistentry><term>MOUNT</term><listitem>
+If this property is true, the changer try to mount the removable disk if nothing is mounted. The system must be configured to allow the amanda user to mount it.
+</listitem></varlistentry>
+<!-- ==== -->
+<varlistentry><term>NUM-SLOT</term><listitem>
+The minimum number of slots in the changer, where the first slot is <computeroutput>slot1</computeroutput>. If additional slot directories exist, they will also be used.
+</listitem></varlistentry>
+<!-- ==== -->
+<varlistentry><term>REMOVABLE</term><listitem>
+If this property is true, then the changer will verify that the changer
+directory (e.g., <filename>/var/mnt/vtapes</filename>) is on a different
+filesystem from its parent directory (e.g., <filename>/var/mnt</filename>).
+This is useful for removable disks, as it will prevent Amanda from creating
+slot directories when the removable disk is not mounted.
+</listitem></varlistentry>
+<!-- ==== -->
+<varlistentry><term>UMOUNT</term><listitem>
+If this property is true, the changer try to umount the removable disk when it exit. The system must be configured to allow the amanda user to umount it.

+<varlistentry><term>UMOUNT-LOCKFILE</term><listitem>
+If UMOUNT is set, it require a lockfile outside of the mount point to prevent race.

+<!-- ==== -->
+<varlistentry><term>UMOUNT-IDLE</term><listitem>
+If set, the changer try to umount the removable disk when it is not in use. The umount-idle value is a delay in second to wait before doing the umount. A value >= 1 is required to prevent useless mount/umount.
