Hi to all,
here is a new patch for bb's devfsd. The news are:
1) Size reduction for the basic setup with no options compiled in from :
text data bss dec hex filename
10591 392 543 11526 2d06 devfsd.o
rw-r--r-- 1 root root 18536 Dec 18 21:52 devfsd.o
to:
text data bss dec hex filename
9303 392 543 10238 27fe devfsd.o
rw-r--r-- 1 root root 16528 Dec 18 22:02 devfsd.o
With this setup you should not expect much output from devfsd
( just at start or with -v) and if some error occurs it only exits 1.
To have more output enable: " Increases logging (and size)" (+1568 b).
2) The option "Adds function names to program output" was removed from config menu
and now to enable debug output you can use bb's standard option:
"Build BusyBox with Debugging symbols".
Be careful as with this option enabled a lot of data are outputted to /dev/log and/or to stderr.
3) A new option: "Enables the -fg and -np option" was added to config menu (+128 b).
BTW: option "Adds support for MODLOAD keyword in devsfd.conf" adds 268 b.
4) The following keywords in devsfd.conf are supported:
"CLEAR_CONFIG", "INCLUDE", "OPTIONAL_INCLUDE", "RESTORE",
"PERMISSIONS", "EXECUTE", "COPY", "IGNORE", "MKOLDCOMPAT",
"MKNEWCOMPAT","RMOLDCOMPAT", "RMNEWCOMPAT".
But only if they are written UPPERCASE!!!!!!!!
5)Help text in usage.h was modified.
6)Something that I have forgotten..........
I've tested this for the last week on my box and it seems to work as expected.
Thanks in advance and please apply.
Ciao,
Tito

BusyBox combines tiny versions of many common UNIX utilities into a single
small executable. It provides minimalist replacements for most of the utilities
you usually find in fileutils, shellutils, findutils, textutils, grep, gzip,
tar, etc. BusyBox provides a fairly complete POSIX environment for any small or
embedded system. The utilities in BusyBox generally have fewer options than
their full featured GNU cousins; however, the options that are included provide
the expected functionality and behave very much like their GNU counterparts.
BusyBox was originally written to support the Debian Rescue/Install disks, but
it also makes an excellent environment for any small or embedded system.
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, /etc, and a kernel.
As of version 0.20 there is now a version number. : ) Also as of version 0.20,
BusyBox is now modularized to easily allow you to build only the components you
need, thereby reducing binary size. Run 'make config' or 'make menuconfig'
for select the functionality that you wish to enable.
After the build is complete, a busybox.links file is generated. This is
used by 'make install' to create symlinks to the busybox binary for all
compiled in functions. By default, 'make install' will place the symlink
forest into `pwd`/_install unless you have defined the PREFIX environment
variable (i.e., 'make PREFIX=/tmp/foo install')
If you wish to install hardlinks, rather than symlinks, you can use
'make install-hardlinks' instead.
----------------
Supported architectures:
Busybox in general will build on any architecture supported by gcc. It has
a few specialized features added for __sparc__ and __alpha__. insmod
functionality is currently limited to x86, ARM, SH3/4, powerpc, m68k,
MIPS, cris, and v850e.
Supported libcs:
glibc-2.0.x, glibc-2.1.x, glibc-2.2.x, glibc-2.3.x, uClibc. People
are looking at newlib and diet-libc, but consider them unsupported,
untested, or worse. Linux-libc5 is no longer supported -- you
should probably use uClibc instead if you want a small C library.
Supported kernels:
Full functionality requires Linux 2.2.x or better. A large fraction of the
code should run on just about anything. While the current code is fairly
Linux specific, it should be fairly easy to port the majority of the code
to, say, FreeBSD or Solaris, or MacOsX, or even Windows (if you are into that
sortof thing).

Getting help:
When you find you need help, you can check out the BusyBox mailing list
archives at http://busybox.net/lists/busybox/ or even join
the mailing list if you are interested.
----------------
Bugs:
If you find bugs, please submit a detailed bug report to the busybox mailing
list at busybox@mail.busybox.net. A well-written bug report should include a
transcript of a shell session that demonstrates the bad behavior and enables
anyone else to duplicate the bug on their own machine. The following is such
an example:
To: busybox@mail.busybox.net
From: diligent@testing.linux.org
Subject: /bin/date doesn't work
Package: busybox
Version: 1.00
When I execute Busybox 'date' it produces unexpected results.
With GNU date I get the following output:
$ date
Wed Mar 21 14:19:41 MST 2001
But when I use BusyBox date I get this instead:
$ date
llegal instruction
I am using Debian unstable, kernel version 2.4.19-rmk1 on an Netwinder,
and the latest uClibc from CVS. Thanks for the wonderful program!

Note the careful description and use of examples showing not only what BusyBox
does, but also a counter example showing what an equivalent GNU app does. Bug
reports lacking such detail may never be fixed... Thanks for understanding.

FTP:
Source for the latest released version, as well as daily snapshots, can always
be downloaded from
http://busybox.net/downloads/
----------------
CVS:
BusyBox now has its own publicly browsable CVS tree at:
http://busybox.net/cgi-bin/cvsweb/busybox/
Anonymous CVS access is available. For instructions, check out:
http://busybox.net/cvs_anon.html
For those that are actively contributing there is even CVS write access:
