Enabling this feature allows automatic mounting of files (containing

filesystem images) via the linux kernel's loopback devices. The mount

command will detect you are trying to mount a file instead of a block

device, and transparently associate the file with a loopback device.

The umount command will also free that loopback device.

You can still use the 'losetup' utility (to manually associate files
|

with loop devices) if you need to do something advanced, such as

Historically, Unix systems kept track of the currently mounted
|
|
partitions in the file "/etc/mtab". These days, the kernel exports
|
|
the list of currently mounted partitions in "/proc/mounts", rendering
|
|
the old mtab file obsolete. (In modern systems, /etc/mtab should be
|
|
a symlink to /proc/mounts.)
|
|
|
|
The only reason to have mount maintain an /etc/mtab file itself is if
|
|
your stripped-down embedded system does not have a /proc directory.
|
|
If you must use this, keep in mind it's inherently brittle (for
|
|
example a mount under chroot won't update it), can't handle modern
|
|
features like separate per-process filesystem namespaces, requires
|
|
that your /etc directory be writeable, tends to get easily confused
|
|
by --bind or --move mounts, won't update if you rename a directory
|
|
that contains a mount point, and so on. (In brief: avoid.)
|
|
|
|
About the only reason to use this is if you've removed /proc from
|
|
your kernel.
