- 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 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
+ specify an offset or cryptographic options to the loopback device.

- depends on BUSYBOX_CONFIG_FEATURE_MTAB_SUPPORT
- help
- 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.
+ 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, and so on. (In brief: avoid.)
