Subject: /bin/true doesn't work
Package: busybox
Version: 0.48
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:
$ /bin/true ; echo $?
1
With GNU /bin/true, I get the following output:
$ /bin/true ; echo $?
0
I am using Debian 2.2r2, kernel version 2.2.18, 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 take a _long_ time to be fixed... Thanks for
understanding.

Currently, busybox bypasses libc NSS. Some folks might want that,
so perhaps adding in the option to choose whether to go to libc for
things like getpwnam() or whether to use the busybox version might
be nice.
