Last change on this file since 956 was 821, checked in by bruno, 13 years ago

Addition of busybox 1.2.1 as a mindi-busybox new package
This should avoid delivering binary files in mindi not built there (Fedora and Debian are quite serious about that)

9    bool "dmesg"
10    default n
11    help
12      dmesg is used to examine or control the kernel ring buffer.  When the
13      Linux kernel prints messages to the system log, they are stored in
14      the kernel ring buffer.  You can use dmesg to print the kernel's ring
15      buffer, clear the kernel ring buffer, change the size of the kernel
16      ring buffer, and change the priority level at which kernel messages
17      are also logged to the system console.  Enable this option if you
18      wish to enable the 'dmesg' utility.

23    help
24      fbset is used to show or change the settings of a Linux frame buffer

49    bool "fdflush"
50    default n
51    help
52      fdflush is only needed when changing media on slightly-broken
53      removable media drives.  It is used to make Linux believe that a
54      hardware disk-change switch has been actuated, which causes Linux to
55      forget anything it has cached from the previous media.  If you have
56      such a slightly-broken drive, you will need to run fdflush every time
57      you change a disk.  Most people have working hardware and can safely
58      leave this disabled.

136    help
137      Linux allows you to create ramdisks.  This utility allows you to
138      delete them and completely free all memory that was used for the
139      ramdisk.  For example, if you boot Linux into a ramdisk and later
140      pivot_root, you may want to free the memory that is allocated to the
141      ramdisk.  If you have no use for freeing memory from a ramdisk, leave

149      with little overhead.  It is not a journaling filesystem however and
150      can experience corruption if it is not properly unmounted or if the

180      lines to make it easy to write complex shell scripts that also check
181      for legal (and illegal) options.  If you want to write horribly
182      complex shell scripts, or use some horribly complex shell script

296    help
297      The mkswap utility is used to configure a file or disk partition as
298      Linux swap space.  This allows Linux to use the entire file or
299      partition as if it were additional RAM, which can greatly increase
300      the capability of low-memory machines.  This additional memory is
301      much slower than real RAM, but can be very helpful at preventing your
302      applications being killed by the Linux out of memory (OOM) killer.
303      Once you have created swap space using 'mkswap' you need to enable

322      the screen, and you are using anything faster than a 300 baud modem,
323      you will probably find this utility very helpful.  If you don't have

337config CONFIG_MOUNT
338    bool "mount"
339    default n
340    help
341      All files and filesystems in Unix are arranged into one big directory
342      tree.  The 'mount' utility is used to graft a filesystem onto a
343      particular part of the tree.  A filesystem can either live on a block
344      device, or it can be accessible over the network, as is the case with
345      NFS filesystems.  Most people using BusyBox will also want to enable

359      The pivot_root utility swaps the mount points for the root filesystem
360      with some other mounted filesystem.  This allows you to do all sorts
361      of wild and crazy things with your Linux system and is far more
362      powerful than 'chroot'.

406      The switch_root utility is used from initramfs to select a new
407      root device.  Under initramfs, you have to use this instead of
408      pivot_root.  (Stop reading here if you don't care why.)
409
410      Booting with initramfs extracts a gzipped cpio archive into rootfs
411      (which is a variant of ramfs/tmpfs).  Because rootfs can't be moved
412      or unmounted*, pivot_root will not work from initramfs.  Instead,
413      switch_root deletes everything out of rootfs (including itself),
414      does a mount --move that overmounts rootfs with the new root, and
415      then execs the specified init program.

444    help
445      Enabling this feature allows automatic mounting of files (containing
446      filesystem images) via the linux kernel's loopback devices.  The mount
447      command will detect you are trying to mount a file instead of a block
448      device, and transparently associate the file with a loopback device.
449      The umount command will also free that loopback device.
450
451      You can still use the 'losetup' utility (to manually associate files
452          with loop devices) if you need to do something advanced, such as
453      specify an offset or cryptographic options to the loopback device.
454      (If you don't want umount to free the loop device, use "umount -D".)

458    default n
459    depends on CONFIG_MOUNT || CONFIG_UMOUNT
460    help
461      Historically, Unix systems kept track of the currently mounted
462      partitions in the file "/etc/mtab".  These days, the kernel exports
463      the list of currently mounted partitions in "/proc/mounts", rendering
464      the old mtab file obsolete.  (In modern systems, /etc/mtab should be
465      a symlink to /proc/mounts.)
466
467      The only reason to have mount maintain an /etc/mtab file itself is if
468      your stripped-down embedded system does not have a /proc directory.
469      If you must use this, keep in mind it's inherently brittle (for
470      example a mount under chroot won't update it), can't handle modern
471      features like separate per-process filesystem namespaces, requires
472      that your /etc directory be writeable, tends to get easily confused
473      by --bind or --move mounts, won't update if you rename a directory
474      that contains a mount point, and so on.  (In brief: avoid.)
475
476      About the only reason to use this is if you've removed /proc from
477      your kernel.
