+        * 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.
+	* 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.
