BusyBox has been written with size-optimization and limited resources in mind.
It is also extremely modular so you can easily include or exclude commands (or
features) at compile time. This makes it easy to customize your embedded
-systems. To create a working system, just add /dev, a kernel, and an editor,
-such as nano, e3, or elvis-tiny. For a really minimal system, you can even use

BusyBox was originally written to support the Debian Rescue/Install disks, but
it also makes an excellent environment for any small or embedded system.
Subject: /bin/true doesn't work
Package: busybox
- Version: 0.48
+ Version: 0.51
When I invoke '/bin/true' it doesn't work. I expected it to return
a "0" but it returned a "1" instead. Here is the transcript:

Many thanks to go to Lineo for paying me to work on busybox.

* The busybox shell, lash, is really too weak for serious use, although it is

+ <br>
+
+ BusyBox 0.51 (the "rock-solid release") is now out there. This
+ release adds only 2 new applets: env and vi. The vi applet,
+ contributed by Sterling Huxley, is very functional, and is only
+ 22k. This release fixes 3 critical bugs in the 0.50 release.
+ There were 2 potential segfaults in lash (the busybox shell) in
+ the 0.50 release which are now fixed. Another critical bug in
+ 0.50 which is now fixed: syslogd from 0.50 could potentially
+ deadlock the init process and thereby break your entire system.
+ <p>
+
+ There are a number of improvements in this release as well. For
+ one thing, the wget applet is greatly improved. Dmitry Zakharov
+ added FTP support, and Laurence Anderson make wget fully RFC
+ compliant for HTTP 1.1. The mechanism for including utility
+ functions in previous releases was clumsy and error prone. Now
+ all utility functions are part of a new libbb library, which makes
+ maintaining utility functions much simpler. And BusyBox now
+ compiles on itanium systems (thanks to the Debian itanium porters
+ for letting me use their system!).
+ <p>
+ You can read the
+ <a href="ftp://oss.lineo.com/busybox/Changelog">changelog</a> for
+ complete details. BusyBox 0.51 can be downloaded from
