The busybox applet provides general help regarding busybox and
allows the included applets to be listed. It's also required
if applet links are to be installed at runtime.
If you can live without these features disabling this will save
some space.
And this is also expected:
$ ./busybox
busybox: applet not found
when executed immediately after build? And this too?
$ ./busybox --help
-help: applet not found
$ ./busybox --list
-list: applet not found
Yes, adding or removing those behaviors is precisely the purpose of
the CONFIG_BUSYBOX setting.
Is it? I didn't realize that and I still don't :(
Maybe you should explain your situation and what you expected?
because a person reading your subject line would assume you are
trying to say "I compiled busybox without the CONFIG_BUSYBOX flag,
and now I'm surprised that it did what it said it would do"...
Alright. My bad. I'll go back and read the ML...
So, I went back and re-read the "Make busybox an applet" threads where
"turn off help and list of applets" is mentioned.

And my understandig now is that if CONFIG_BUSYBOX=y, the '--help',
'--list' and '--list-full' options are removed, and at the same time
adds about 900 bytes to the binary.
I may be thick, but what I still don't understand is what benefits
does that bring?
This thing is meant for people who are in real squeeze and don't want
any more functionality than they absolutely must have.
If they configured 20 applets they need and they prepare their filesystem
so that the /bin/foo -> /bin/busybox links are created by means
other than busybox --install, they don't need the code which says this:
Hi,
I think at least this part of text should be mandatory
with every possible config.
"BusyBox is copyrighted by many authors between 1998-2015.
Licensed under GPLv2. See source distribution for detailed
copyright notices."
Eventually reduced to:
Busybox V. x.xx.x (C) GPLv2 1998-2016
The usage text etc. could be optional.
BTW we should update the year of the copyright text
to 1998-2016.
Ciao,
Tito
Usage: busybox [function [arguments]...]
or: busybox --list[-full]
or: busybox --install [-s] [DIR]
or: function [arguments]...
BusyBox is a multi-call binary that combines many common Unix
utilities into a single executable. Most people will create a
link to busybox for each function they wish to use and BusyBox
will act like whatever it was invoked as.
It's just useless bloat for them. Now they can switch it off.
OTOH, you do want that code to be present. Thus, please turn CONFIG_BUSYBOX=y.
