The

|
|
|
-command will free the loop device (if any) associated with the mount, in
|
|

|
|

-using 'losetup -d', see
|

|

-.BR losetup (8).

|
+command will automatically detach loop device previously initialized by

|

+.BR mount (8)
|
|
|
|
|
+command independently of /etc/mtab.
|
|
|
|

+
|
|
|
|
|
+In this case the device is initialized with "autoclear" flag (see
|
|
|
|
|
+.BR losetup (8)
|
|
|
|
|
+output for more details), otherwise it's necessary to use the option \fB \-\-detach\-loop\fR
|
|
|
|
|
+or call \fBlosetup -d <device>\fR. The autoclear feature is supported since Linux 2.6.25.
