BusyBox has been written with size-optimization and limited resources in mind.

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 $?

It would be a very nice thing to reduce this list to an absolute minimum, and

for GNU libc to be so big. I'm sure it can be a lot better.

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.
