 880         switch_root deletes everything out of rootfs (including itself),

 949         Enabling this feature allows automatic mounting of files (containing
 950         filesystem images) via the linux kernel's loopback devices.
 951         The mount command will detect you are trying to mount a file instead
 952         of a block device, and transparently associate the file with a
 953         loopback device. The umount command will also free that loopback
 954         device.
 955
 956         You can still use the 'losetup' utility (to manually associate files
 957         with loop devices) if you need to do something advanced, such as
 958         specify an offset or cryptographic options to the loopback device.

 979         Historically, Unix systems kept track of the currently mounted
 980         partitions in the file "/etc/mtab". These days, the kernel exports
 981         the list of currently mounted partitions in "/proc/mounts", rendering
 982         the old mtab file obsolete. (In modern systems, /etc/mtab should be
 983         a symlink to /proc/mounts.)
 984
 985         The only reason to have mount maintain an /etc/mtab file itself is if
 986         your stripped-down embedded system does not have a /proc directory.
 987         If you must use this, keep in mind it's inherently brittle (for
 988         example a mount under chroot won't update it), can't handle modern
 989         features like separate per-process filesystem namespaces, requires
 990         that your /etc directory be writable, tends to get easily confused
 991         by --bind or --move mounts, won't update if you rename a directory
 992         that contains a mount point, and so on. (In brief: avoid.)
 993
 994         About the only reason to use this is if you've removed /proc from
 995         your kernel.
