| 11 | default BUSYBOX_DEFAULT_ACPID |
| 12 | help |
| 13 | acpid listens to ACPI events coming either in textual form from |
| 14 | /proc/acpi/event (though it is marked deprecated it is still widely |
| 15 | used and _is_ a standard) or in binary form from specified evdevs |
| 16 | (just use /dev/input/event*). |
| 17 | |
| 18 | It parses the event to retrieve ACTION and a possible PARAMETER. |
| 19 | It then spawns /etc/acpi/<ACTION>[/<PARAMETER>] either via run-parts |
| 20 | (if the resulting path is a directory) or directly as an executable. |
| 21 | |
| 22 | N.B. acpid relies on run-parts so have the latter installed. |

| 905 | Enabling this feature allows automatic mounting of files (containing |
| 906 | filesystem images) via the linux kernel's loopback devices. |
| 907 | The mount command will detect you are trying to mount a file instead |
| 908 | of a block device, and transparently associate the file with a |
| 909 | loopback device. The umount command will also free that loopback |
| 910 | device. |
| 911 | |
| 912 | You can still use the 'losetup' utility (to manually associate files |
| 913 | with loop devices) if you need to do something advanced, such as |
| 914 | specify an offset or cryptographic options to the loopback device. |
| 915 | (If you don't want umount to free the loop device, use "umount -D".) |

| 921 | help |
| 922 | Linux kernels >= 2.6.24 support unlimited loopback devices. They are |
| 923 | allocated for use when trying to use a loop device. The loop device |
| 924 | must however exist. |
| 925 | |
| 926 | This feature lets mount to try to create next /dev/loopN device |
| 927 | if it does not find a free one. |

| 935 | Historically, Unix systems kept track of the currently mounted |
| 936 | partitions in the file "/etc/mtab". These days, the kernel exports |
| 937 | the list of currently mounted partitions in "/proc/mounts", rendering |
| 938 | the old mtab file obsolete. (In modern systems, /etc/mtab should be |
| 939 | a symlink to /proc/mounts.) |
| 940 | |
| 941 | The only reason to have mount maintain an /etc/mtab file itself is if |
| 942 | your stripped-down embedded system does not have a /proc directory. |
| 943 | If you must use this, keep in mind it's inherently brittle (for |
| 944 | example a mount under chroot won't update it), can't handle modern |
| 945 | features like separate per-process filesystem namespaces, requires |
| 946 | that your /etc directory be writable, tends to get easily confused |
| 947 | by --bind or --move mounts, won't update if you rename a directory |
| 948 | that contains a mount point, and so on. (In brief: avoid.) |
| 949 | |
| 950 | About the only reason to use this is if you've removed /proc from |
| 951 | your kernel. |
