config FEATURE_MOUNT_LOOP
	bool "Support loopback mounts"
	default y
	depends on MOUNT || UMOUNT
	help
	  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.
	  (If you don't want umount to free the loop device, use "umount -D".)

config FEATURE_MOUNT_LOOP_CREATE
	bool "Create new loopback devices if needed"
	default y
	depends on FEATURE_MOUNT_LOOP
	help
	  Linux kernels >= 2.6.24 support unlimited loopback devices. They are
	  allocated for use when trying to use a loop device. The loop device
	  must however exist.

	  This feature lets mount to try to create next /dev/loopN device
	  if it does not find a free one.

config FEATURE_MTAB_SUPPORT
	bool "Support old /etc/mtab file"
	default n
	depends on MOUNT || UMOUNT
	select FEATURE_MOUNT_FAKE
	help
	  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 writable, 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.
