Yes. halt, reboot, and poweroff are incompatible with SysVinit, since
they use signals to communicate with init. Sysvinit uses a named pipe
for such things. I can see that this could be confusing though, so making
halt/reboot/poweroff compatible with SysVinit would be better.
This falls into the category of a wishlist bug.

Do you absolutely need POSIXLY_CORRECT? Can you not use 'du -k'?

I'll leave these to Mark. Mark?

Not supported right now. Is there another way to do what
you need? If not I suppose we could add in such a thing.

true. Need bytes?

Nope. operators like -or, -and, anf ! are not supported.

Nope. Need it?

As in recursively display the inode of each directory under the cwd?
I don't think even GNU ls does that...
[andersen at slag busybox]$ ls --version | head -n 1
ls (GNU fileutils) 4.0x
[andersen at slag busybox]$ unalias ls
[andersen at slag busybox]$ ls -Rid
754598 .
[andersen at slag busybox]$ ./busybox ls -Rid
754598 .
