- Enabling this feature allows mount to use the '-o' loop options,
- which lets you loop mount files. Mount will automagically setup and
- free the necessary loop devices so you do not need to mess with the
- 'losetup' utility unless you really want to. This is really
- only useful if you plan to loop mount files.
+ Enabling this feature allows automatic loopback mounts, meaning you can mount
+ filesystems contained in normal files as well as in block devices. The mount
+ and umount commands will detect you are trying to mount a file instead of a
+ block device, and transparently associate it with a loopback device (and free
+ the loopback device on unmount) for you.
+
+ You can still use the 'losetup' utility and mount the loopback device yourself
+ if you need to do something advanced, such as specify an offset or cryptographic
+ options to the loopback device.

- Some people have a read only root filesystem, but they also wish to
- have the 'mount' utility create an mtab file listing the filesystems
- which have been mounted. This option allows you to specify an alternative
- location for the mtab file, such as /var/mtab, or /tmp/mtab. The default
- value is /etc/mtab, which is where this file is located on most desktop
- Linux systems.
+ Note that even non-embedded developers probably want to have /etc/mtab
+ be a symlink to /proc/mounts, since otherwise mtab can get out of sync
+ with the real kernel mount state in numerous ways.
