| 614 | The switch_root utility is used from initramfs to select a new |

| 618 | Booting with initramfs extracts a gzipped cpio archive into rootfs |
| 619 | (which is a variant of ramfs/tmpfs). Because rootfs can't be moved |
| 620 | or unmounted*, pivot_root will not work from initramfs. Instead, |
| 621 | switch_root deletes everything out of rootfs (including itself), |
| 622 | does a mount --move that overmounts rootfs with the new root, and |
| 623 | then execs the specified init program. |

| 654 | Enabling this feature allows automatic mounting of files (containing |
| 655 | filesystem images) via the linux kernel's loopback devices. |
| 656 | The mount command will detect you are trying to mount a file instead |
| 657 | of a block device, and transparently associate the file with a |

| 661 | You can still use the 'losetup' utility (to manually associate files |
| 662 | with loop devices) if you need to do something advanced, such as |

| 683 | help |
| 684 | Historically, Unix systems kept track of the currently mounted |
| 685 | partitions in the file "/etc/mtab". These days, the kernel exports |
| 686 | the list of currently mounted partitions in "/proc/mounts", rendering |
| 687 | the old mtab file obsolete. (In modern systems, /etc/mtab should be |
| 688 | a symlink to /proc/mounts.) |
| 689 | |
| 690 | The only reason to have mount maintain an /etc/mtab file itself is if |
| 691 | your stripped-down embedded system does not have a /proc directory. |
| 692 | If you must use this, keep in mind it's inherently brittle (for |
| 693 | example a mount under chroot won't update it), can't handle modern |
| 694 | features like separate per-process filesystem namespaces, requires |
| 695 | that your /etc directory be writable, tends to get easily confused |
| 696 | by --bind or --move mounts, won't update if you rename a directory |
| 697 | that contains a mount point, and so on. (In brief: avoid.) |
| 698 | |
| 699 | About the only reason to use this is if you've removed /proc from |
| 700 | your kernel. |
