| 818 | then execs the specified init program. |

| 848 | Enabling this feature allows automatic mounting of files (containing |

| 850 | The mount command will detect you are trying to mount a file instead |

| 865 | help |
| 866 | Historically, Unix systems kept track of the currently mounted |
| 867 | partitions in the file "/etc/mtab". These days, the kernel exports |
| 868 | the list of currently mounted partitions in "/proc/mounts", rendering |
| 869 | the old mtab file obsolete. (In modern systems, /etc/mtab should be |
| 870 | a symlink to /proc/mounts.) |
| 871 | |
| 872 | The only reason to have mount maintain an /etc/mtab file itself is if |
| 873 | your stripped-down embedded system does not have a /proc directory. |
| 874 | If you must use this, keep in mind it's inherently brittle (for |
| 875 | example a mount under chroot won't update it), can't handle modern |
| 876 | features like separate per-process filesystem namespaces, requires |
| 877 | that your /etc directory be writeable, tends to get easily confused |
| 878 | by --bind or --move mounts, won't update if you rename a directory |
| 879 | that contains a mount point, and so on. (In brief: avoid.) |
| 880 | |
| 881 | About the only reason to use this is if you've removed /proc from |
| 882 | your kernel. |
