 753           list of active mount points. That's why.

 760           When you want to remove a mounted filesystem from its current mount
 761           point, for example when you are shutting down the system, the
 762           'umount' utility is the tool to use. If you enabled the 'mount'
 763           utility, you almost certainly also want to enable 'umount'.

 780           Enabling this feature allows automatic mounting of files (containing
 781           filesystem images) via the linux kernel's loopback devices.
 782           The mount command will detect you are trying to mount a file instead
 783           of a block device, and transparently associate the file with a
 784           loopback device. The umount command will also free that loopback
 785           device.
 786
 787           You can still use the 'losetup' utility (to manually associate files
 788           with loop devices) if you need to do something advanced, such as
 789           specify an offset or cryptographic options to the loopback device.
 790           (If you don't want umount to free the loop device, use "umount -D".)

 797           Linux kernels >= 2.6.24 support unlimited loopback devices. They are

 799           must however exist.
 800

 802           if it does not find a free one.

 810           Historically, Unix systems kept track of the currently mounted
 811           partitions in the file "/etc/mtab". These days, the kernel exports
 812           the list of currently mounted partitions in "/proc/mounts", rendering
 813           the old mtab file obsolete. (In modern systems, /etc/mtab should be
 814           a symlink to /proc/mounts.)
 815
 816           The only reason to have mount maintain an /etc/mtab file itself is if
 817           your stripped-down embedded system does not have a /proc directory.
 818           If you must use this, keep in mind it's inherently brittle (for
 819           example a mount under chroot won't update it), can't handle modern
 820           features like separate per-process filesystem namespaces, requires
 821           that your /etc directory be writable, tends to get easily confused
 822           by --bind or --move mounts, won't update if you rename a directory
 823           that contains a mount point, and so on. (In brief: avoid.)
 824
 825           About the only reason to use this is if you've removed /proc from
 826           your kernel.
