 755           Enabling this feature allows automatic mounting of files (containing
 756           filesystem images) via the linux kernel's loopback devices.
 757           The mount command will detect you are trying to mount a file instead
 758           of a block device, and transparently associate the file with a
 759           loopback device. The umount command will also free that loopback
 760           device.
 761
 762           You can still use the 'losetup' utility (to manually associate files
 763           with loop devices) if you need to do something advanced, such as
 764           specify an offset or cryptographic options to the loopback device.
 765           (If you don't want umount to free the loop device, use "umount -D".)

 772           Linux kernels >= 2.6.24 support unlimited loopback devices. They are
 773           allocated for use when trying to use a loop device. The loop device
 774           must however exist.
 775
 776           This feature lets mount to try to create next /dev/loopN device
 777           if it does not find a free one.

 785           Historically, Unix systems kept track of the currently mounted
 786           partitions in the file "/etc/mtab". These days, the kernel exports
 787           the list of currently mounted partitions in "/proc/mounts", rendering
 788           the old mtab file obsolete. (In modern systems, /etc/mtab should be
 789           a symlink to /proc/mounts.)
 790
 791           The only reason to have mount maintain an /etc/mtab file itself is if
 792           your stripped-down embedded system does not have a /proc directory.
 793           If you must use this, keep in mind it's inherently brittle (for
 794           example a mount under chroot won't update it), can't handle modern
 795           features like separate per-process filesystem namespaces, requires
 796           that your /etc directory be writable, tends to get easily confused
 797           by --bind or --move mounts, won't update if you rename a directory
 798           that contains a mount point, and so on. (In brief: avoid.)
 799
 800           About the only reason to use this is if you've removed /proc from
 801           your kernel.
