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

38 | |
39 | config DMESG |
40 | bool "dmesg" |
41 | default n |
42 | help |
43 | dmesg is used to examine or control the kernel ring buffer. When the |
44 | Linux kernel prints messages to the system log, they are stored in |
45 | the kernel ring buffer. You can use dmesg to print the kernel's ring |
46 | buffer, clear the kernel ring buffer, change the size of the kernel |
47 | ring buffer, and change the priority level at which kernel messages |
48 | are also logged to the system console. Enable this option if you |
49 | wish to enable the 'dmesg' utility. |
50 | |
51 | config FEATURE_DMESG_PRETTY |
52 | bool "Pretty dmesg output" |
53 | default y |
54 | depends on DMESG |
55 | help |
56 | If you wish to scrub the syslog level from the output, say 'Y' here. |
57 | The syslog level is a string prefixed to every line with the form |
58 | "<#>". |
59 | |
60 | With this option you will see: |

72 | config FBSET |
73 | bool "fbset" |
74 | default n |
75 | help |
76 | fbset is used to show or change the settings of a Linux frame buffer |
77 | device. The frame buffer device provides a simple and unique |
78 | interface to access a graphics display. Enable this option |
79 | if you wish to enable the 'fbset' utility. |
80 | |
81 | config FEATURE_FBSET_FANCY |
82 | bool "Turn on extra fbset options" |
83 | default n |
84 | depends on FBSET |
85 | help |
86 | This option enables extended fbset options, allowing one to set the |
87 | framebuffer size, color depth, etc. interface to access a graphics |
88 | display. Enable this option if you wish to enable extended fbset |
89 | options. |

91 | config FEATURE_FBSET_READMODE |
92 | bool "Turn on fbset readmode support" |
93 | default n |
94 | depends on FBSET |
95 | help |
96 | This option allows fbset to read the video mode database stored by |
97 | default as /etc/fb.modes, which can be used to set frame buffer |
98 | device to pre-defined video modes. |
99 | |
100 | config FDFLUSH |
101 | bool "fdflush" |
102 | default n |
103 | help |
104 | fdflush is only needed when changing media on slightly-broken |
105 | removable media drives. It is used to make Linux believe that a |
106 | hardware disk-change switch has been actuated, which causes Linux to |
107 | forget anything it has cached from the previous media. If you have |
108 | such a slightly-broken drive, you will need to run fdflush every time |
109 | you change a disk. Most people have working hardware and can safely |
110 | leave this disabled. |
111 | |
112 | config FDFORMAT |
113 | bool "fdformat" |
114 | default n |
115 | help |
116 | fdformat is used to low-level format a floppy disk. |
117 | |
118 | config FDISK |
119 | bool "fdisk" |
120 | default n |
121 | help |
122 | The fdisk utility is used to divide hard disks into one or more |
123 | logical disks, which are generally called partitions. This utility |
124 | can be used to list and edit the set of partitions or BSD style |
125 | 'disk slices' that are defined on a hard drive. |

134 | config FEATURE_FDISK_WRITABLE |
135 | bool "Write support" |
136 | default y |
137 | depends on FDISK |
138 | help |
139 | Enabling this option allows you to create or change a partition table |
140 | and write those changes out to disk. If you leave this option |
141 | disabled, you will only be able to view the partition table. |
142 | |
143 | config FEATURE_AIX_LABEL |
144 | bool "Support AIX disklabels" |
145 | default n |
146 | depends on FDISK && FEATURE_FDISK_WRITABLE |
147 | help |
148 | Enabling this option allows you to create or change AIX disklabels. |
149 | Most people can safely leave this option disabled. |

168 | bool "Support BSD disklabels" |
169 | default n |
170 | depends on FDISK && FEATURE_FDISK_WRITABLE |
171 | help |
172 | Enabling this option allows you to create or change BSD disklabels |
173 | and define and edit BSD disk slices. |

175 | config FEATURE_FDISK_ADVANCED |
176 | bool "Support expert mode" |
177 | default n |
178 | depends on FDISK && FEATURE_FDISK_WRITABLE |
179 | help |
180 | Enabling this option allows you to do terribly unsafe things like |
181 | define arbitrary drive geometry, move the beginning of data in a |
182 | partition, and similarly evil things. Unless you have a very good |
183 | reason you would be wise to leave this disabled. |
184 | |
185 | config FINDFS |
186 | bool "findfs" |

194 | config FREERAMDISK |
195 | bool "freeramdisk" |
196 | default n |
197 | help |
198 | Linux allows you to create ramdisks. This utility allows you to |
199 | delete them and completely free all memory that was used for the |
200 | ramdisk. For example, if you boot Linux into a ramdisk and later |
201 | pivot_root, you may want to free the memory that is allocated to the |
202 | ramdisk. If you have no use for freeing memory from a ramdisk, leave |
203 | this disabled. |
204 | |
205 | config FSCK_MINIX |
206 | bool "fsck_minix" |
207 | default n |
208 | help |
209 | The minix filesystem is a nice, small, compact, read-write filesystem |
210 | with little overhead. It is not a journaling filesystem however and |
211 | can experience corruption if it is not properly unmounted or if the |
212 | power goes off in the middle of a write. This utility allows you to |
213 | check for and attempt to repair any corruption that occurs to a minix |
214 | filesystem. |
215 | |
216 | config MKFS_EXT2 |
217 | bool "mkfs_ext2" |

237 | help |
238 | If you wish to be able to create version 2 minix filesystems, enable |
239 | this. If you enabled 'mkfs_minix' then you almost certainly want to |
240 | be using the version 2 filesystem support. |

255 | bool "getopt" |
256 | default n |
257 | help |
258 | The getopt utility is used to break up (parse) options in command |
259 | lines to make it easy to write complex shell scripts that also check |
260 | for legal (and illegal) options. If you want to write horribly |
261 | complex shell scripts, or use some horribly complex shell script |
262 | written by others, this utility may be for you. Most people will |
263 | wisely leave this disabled. |

283 | help |
284 | The hexdump utility is used to display binary data in an ascii |
285 | readable way. This option creates binary data from an ascii input. |
286 | NB: this option is non-standard. It's unwise to use it in scripts |
287 | aimed to be portable. |

299 | help |
300 | The hwclock utility is used to read and set the hardware clock |
301 | on a system. This is primarily used to set the current time on |
302 | shutdown in the hardware clock, so the hardware will keep the |
303 | correct time when Linux is _not_ running. |

429 | help |
430 | The mkswap utility is used to configure a file or disk partition as |
431 | Linux swap space. This allows Linux to use the entire file or |
432 | partition as if it were additional RAM, which can greatly increase |
433 | the capability of low-memory machines. This additional memory is |
434 | much slower than real RAM, but can be very helpful at preventing your |
435 | applications being killed by the Linux out of memory (OOM) killer. |

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

849 | pivot_root. (Stop reading here if you don't care why.) |
850 | |
851 | Booting with initramfs extracts a gzipped cpio archive into rootfs |
852 | (which is a variant of ramfs/tmpfs). Because rootfs can't be moved |
853 | or unmounted*, pivot_root will not work from initramfs. Instead, |
854 | switch_root deletes everything out of rootfs (including itself), |
855 | does a mount --move that overmounts rootfs with the new root, and |
856 | then execs the specified init program. |
857 | |

859 | and ending point for searching through the kernel's doubly linked |
860 | list of active mount points. That's why. |

885 | help |
886 | Enabling this feature allows automatic mounting of files (containing |
887 | filesystem images) via the linux kernel's loopback devices. |
888 | The mount command will detect you are trying to mount a file instead |
889 | of a block device, and transparently associate the file with a |
890 | loopback device. The umount command will also free that loopback |
891 | device. |
892 | |
893 | You can still use the 'losetup' utility (to manually associate files |
894 | with loop devices) if you need to do something advanced, such as |
895 | specify an offset or cryptographic options to the loopback device. |

902 | select FEATURE_MOUNT_FAKE |
903 | help |
904 | Historically, Unix systems kept track of the currently mounted |
905 | partitions in the file "/etc/mtab". These days, the kernel exports |
906 | the list of currently mounted partitions in "/proc/mounts", rendering |
907 | the old mtab file obsolete. (In modern systems, /etc/mtab should be |
908 | a symlink to /proc/mounts.) |
909 | |
910 | The only reason to have mount maintain an /etc/mtab file itself is if |
911 | your stripped-down embedded system does not have a /proc directory. |
912 | If you must use this, keep in mind it's inherently brittle (for |
913 | example a mount under chroot won't update it), can't handle modern |
914 | features like separate per-process filesystem namespaces, requires |
915 | that your /etc directory be writeable, tends to get easily confused |
916 | by --bind or --move mounts, won't update if you rename a directory |
917 | that contains a mount point, and so on. (In brief: avoid.) |
918 | |
919 | About the only reason to use this is if you've removed /proc from |
920 | your kernel. |
