为samsung2410 ARM移植的busybox工具包

	* Fixed rebooting when init runs as an initrd.
	* Fixes and updates from Karl M. Hegbloom  <[e-mail]>
	    - update.c rewritten to look more like update-2.11
	    - moveed the inode hash out of du.c and into utility.c to make 
		it a common resource that can be used by other apps.
	    - cp_mv.c now checks inodes to see if a source and dest are
		the same, and prints an error (instead of endlessly looping).
	    - mv now attempts to do a rename, and will fall back to doing
		a copy only if the rename fails.
	    - Syslogd now supports multiple concurrent connections
	* Several fixes from Pavel Roskin <[e-mail]>:
	    - Fixes to sort.  Removed "-g", fixed and added "-r"
	    - Fixes to the makefile for handling "strip"
	* An initial telnet implementation was added by 
	    Randolph Chung <[e-mail]>.
	* Fixed a bug where "sed 's/foo/bar/g'" (i.e. a script w/o a "-e")
	* ps now supports BB_FEATURE_AUTOWIDTH, and can adjust its width
	    to match the terminal (defaults to width=79 when this is off).
	* ps now accepts (and ignores) all options except for "--help" (which
		as would be expected displays help).
	* Fixed mount'ing loop devices when the filesystem type was not 
	    specified.  It used to revert to non-loop after the first try.
	* all mallocs now use xmalloc (and so are OOM error safe), and
	    the common error handling saves a few bytes.  Thanks to 
	    Bob Tinsley <[e-mail]> for the patch.
	* Fix "+" parsing bug in date, from "Merle F. McClelland" <[e-mail]>.
	* Fix symlink following bug in chmod -R and friends.  
	* Now allows SYSV style 'chown foo:bar' in addition to 'chown foo.bar'
	* Fixed a bug in the busybox globbing routine such that 'find /dir -name [i]' 
	    no longer segfaults.

        * Fairly massive restructuring of umount.c to deal with remounting 
	  busy devices read-only. Adds a -r option to control that; it is 
	  optionally compiled in with BB_FEATURE_REMOUNT
	* Added a bunch of functions to mtab.c to interact with the
	  {get,set,end}mntent interface; as it turns out, those functions do
	  not appear to be re-entrant, and that causes a lot of problems with
	  the way umount was originally written.
	* Makes init send TERM and KILL (instead of HUP and KILL) on reboot
	  to be more consistent with sysvinit
	* Changes to init.c to use the new -r option to umount. Also increased
	  the sleep time between the time the TERM and KILL signals are sent

        - Randolph Chung


	* cp.c, mv.c: removed, replaced by cp_mv.c which has been
	    extensively rewritten from the original cp.c.
	* Fixed cp and mv so if the source and destination are a the
	    same directory it will print an error and continue.
	* Also added a warning message to the `mv' usage string saying that
	    this is not GNU mv, and it will break hard links. cp also breaks
	    hard links.
	* ln.c: implemented `-n' switch, no-deref symlinks.
	* include<sys/param.h>: and use PATH_MAX everywhere.  busybox: File
	* name buffer overrun guards to prevent future crashes.
	    - Always check exit status.
	    - Purge all use of `creat()', replace with `open()'.
	* utility.c 
	    - recursiveAction was overriding the value of followLinks thus
	      ignoring it.
	    - isDirectory now takes a followLinks boolean, updated all callers
	    - copyFile had the followLinks logic reversed.
	* messages.c: New file. Put common error message strings all in
	    one place in an attempt to shrink the binary a little.

	-Karl M. Hegbloom


	* changed fsck_minix.c to reduce its .bss size significantly
	  -beppu -piptigger
	* Made tar creation support in busybox tar optional.  You no longer
	* _have_ to put a "-" in front of tar options.  Tar could inadvertently
	* change permissions and ownership on
	    certain directories pointed to by symlinks.
	* Made grep and grep -h do the right thing wrt printing
	    the file name (it failed to print files names in many cases).
	* Fix a namespace aliasing problem wereby if du was built in, the 
	    symlink for both du and dutmp would be installed, or then rm was
	    built in, the symlinks for both rm and rmmod would be installed.
	* Added a closelog() to init.c after loging -- fix thanks to 
	    Taketoshi Sano <[e-mail]>
	* Rewrote and simplified logger.  Added the "-t" option, and made it
	    behave itself a bit better.
	* Optional support contributed by Ben Collins <[e-mail]> 
	    for the kernel init chroot patch by Werner Almesberger, which
	    allows init to chroot to a new device, and umount the old one.
	* Fixed bug that wouldn't let one chown a symlink -- it would
	    always dereference before.  -beppu
	* Fixed a bug where init could have reference already freed memory.
	    Found and fixed by Taketoshi Sano <[e-mail]>
	* Several contributions from Friedrich Vedder <[e-mail]>
	* Added (and documented) "-n" option for head
	* Cleanup for a number of usage messages -- also 
	    contributed Friedrich Vedder <[e-mail]>
	* Cosmetic fix to busybox.c (Don't print a comma at the
	    end of line if there are no more application names).
	* Fixed a stupid bug in "head" option handling ("head -n" 
	    would segfault).
	* Moved commonly used functions "xmalloc()" and "exit()"
	    to utility.c (with proper #ifdef's).
	* Created a tiny tail implementation, removing -c, -q, -v, and making
	    tail -f work only with a single file.  This reduced tail from 6k to
	    2.4k.  The bigger/more featured tail can still be had by disabling
	    BB_FEATURE_SIMPLE_TAIL in busybox.defs.h
	* Ping now falls back to doing the right thing if /etc/protocols
	    turns up missing.
	* Fixed mount and umount.  Previously they could leak loop device 
	    allocations, causing the system to quickly run out.  Fix for umount
	    by Ben Collins <[e-mail]>, and mount was fixed by me.
	* ls formatting on eight charactor user names fixed by 
	    Randolph Chung <[e-mail]>.
	* cp could, when copying symlinks, change permissions of the
	    files pointed to by the symlinks.
	* Several fixes from Pavel Roskin <[e-mail]>:
	    - `chown' with 1 argument displayed the error incorrectly
	    - `fdflush', `length' and `printf' crashed if run without arguments
	    - `fdflush' tried to flush itself using *argv
	    - added "skip" and "seek" to dd.
	    - ls no longer messus up output when combining files and
	      directories on the command line 
	* swapoff -a was not working.  Now it is.  
	* init did not cleanly unmount filesystems on reboot.  Now it does.  
	* "sed -ne s/foo/bar/" worked but "sed -n -e s/foo/bar/" didn't.
	    Now both work.
	* Some architectures (PowerPc) assume chars are unsigned, so they could
	    not distinguish between EOF and '\0xFF' in sed.  Sed now uses ints.
	* Began converting error handling to use some common routines
	    in utility.c
	* syslogd now has better message handling and ignores SIGHUP.
	* install.sh had a bug preventing installation to the specified
	    target directory.  Fix from Gilbert Coville <[e-mail]>
	* You can now spefify alternative strip commands -- change 
	    also from Gilbert Coville.

0.41
	* New Apps: wc, hostid, logname, tty, whoami, yes -- all contributed 
	    by Edward Betts <[e-mail]>
	* Fixed a bug in both cp and mv preventing 'cp foo/README bar'
	    type commands (file in a directory to another directory) from
	    working.
	* Fixed a logger bug that caused garbage to be written to the syslog 
	    (unless you used busybox syslog, which hid the bug).  Thanks to
	    Alex Holden <[e-mail]> for the fix.
	* /bin/true and /bin/false were echoing a blank line when run.  
	    Now fixed.
	* mkdir -p would print an error when asked to mkdir an existing dir
	    with no interveining subdirectories.
	* Fixed "syslogd -O" so that it works.  Added -o loop option for mount,
	* and support in umount for loop
	  devices. Support is toggled by MOUNT_LOOP feature -- Ben Collins
	  <[e-mail]>
	* Several fixes from Marco Pantaleoni <[e-mail]> compile in
	* fullWrite() not only if BB_TAR is defined, but also
		if BB_CP or BB_MV are (fullWrite() is referenced by copyFile())
	    * add some compiler optimizations to further reduce executable size
		(as a side note, on my machines the largest code is generated
		by gcc 2.95.2 with -Os ! The smallest by plain gcc 2.7.2.3 with
		-O2 -m386 ...)
	    * Compile now won't fail if busybox.def.h defines 
		BB_FEATURE_LINUXRC but not BB_INIT.  (init_main used to be
		referenced, but not compiled)
	* Fixed a bug in setting TERM for serial console support.  TERM now
	    defaults to "ansi" for serial consoles.
	* Fixed a bug in handling the CONSOLE env. variable for serial
	* consoles.

0.40
	* New Apps: sort, uniq. -beppu New Apps: lsmod, rmmod -erik New Apps:
	* fbset contributed by Randolph Chung <[e-mail]>.  New App::
	* loadacm contributed by Peter Novodvorsky <[e-mail]>
	    for loading application character maps for Unicode fonts.
	* Major init re-work.  init now supports inittab (slightly different
	    but similar to sysvinit), allowing me to get all the policy out of
	    init and into the conf file.  It works just fine without inittab
	    being present, but if you dont like the default behavior you can
	    now do something about it.  Init is much cleaner as a result.
	* Fixed an bug in syslogd causing it to stop after 20 minutes. -erik
	* Fixed an embarrasing segfault in head	-beppu Fixed the embarrasing
	* failure of 'logger -p'. -erik Added the -s option to du -beppu
	* Re-worked the source tree a bit so it will compile under glibc 2.0.7 
	    with the 2.0.x Linux kernel.
	* Added 'grep -q' thanks to a patch from "Konstantin Boldyshev" 
	    <[e-mail]>.
	* Grep -i previously failed on UPPER CASE patterns due to a silly 
	    regexp implementation bug that is now fixed.
	* Fixed a bug where tar would set, and then clear SGID and SUID bits.
	* Fixed a bug where tar would not set the user and group on device
	    special files.
	* Fixed a bug where tar would not restore the time to files.  Fixed a
	* major security problem with tar -- it changed ownership 
	    of any file pointed to by a symlink to 777 (like say libc....)
	    Ouch!!!
	* cp and mv were very broken when moving directories.  I have rewritten 
	    them so they should now work as expected. 
	* sed now supports addresses (numeric or regexp, with negation) and 
	    has an append command, thanks to Marco Pantaleoni <[e-mail]>
	* Fixed dmesg.  It wasn't parsing its options (-n or -s) properly.
	* Some cosmetic fixes to ls output formatting to make it behave more
	    like GNU ls.
	* Fixed a stupid segfault in kill.  Several fixes from Friedrich Vedder
	* <[e-mail]>:
	    - Added gunzip -t, removed gunzip.c dead code,
	    - fixed several typos
	    - Glibc 2.0.7 and libc5 compile fixes
	* Fixed a bug where 'mknod --help' would segfault.

0.39 
	* New Apps: ping, hostname, and mkfifo contributed by Randolph Chung
	    <[e-mail]>.  3 items off the TODO list!
	* I wrote free (just calls "cat /proc/meminfo").  Added tail, based on
	* tail from GNU textutils-1.19, but adjusted
	    to suit my evil purposes.  Costs 6k.  I'll make it smaller
	    sometime.
	* on reboot, init called 'umount -a -n', which caused errors
	    when BB_MTAB was not enabled.  Changed to 'umount -a', which does
	    the right thing.
	* init will now try to run /sbin/getty if it is present (for easy
	    integration with the about-to-be-released tinylogin.)
	* kill now behaves itself properly, added 'kill -l' to list signals 'ls
	* -l' was failing on long directories, since my_getid was leaking 
	    one file descriptor per file.  Oops.
	* Fixed rebooting from init.  I'd accidently left some debugging code
	* in
	    which blocked reboots.
	* Fixed reboot, halt (and added poweroff) such that they handle it when
	    init is not at PID 1 (like when running in an initrd).
	* Added a prelinary du implementation.  Some parameter parsing
	    stuff still needs to be added. -beppu (John Beppu
	    <[e-mail]>)
	* Implemented tee.  -beppu Implemented head. -beppu

0.38
	* Fixed a segfault in 'umount -a' when a badly formed /etc/fstab
	    file existed.
	* df will not exit on error, but will stat all mounted filesystems.
	* Fixed tar so uid/gid/permissions on extracted tarballs will be 
	    correct.
	* Fixed find -name so it properly uses shell wildcard patterns 
	    (i.e. `*', `?', and `[]') instead of regular expressions, which
	    was causing some confusing and unexpected behavior.
	* Added klogd to syslogd, so now the log will contain both system and
	    kernel messages.
	* syslogd now creates the /dev/log socket to make sure it is there, and
