coreutils: Unknown program should fail (tests/misc/coreutils.sh)

[oech3]

The GNU multi-call coreutils does

$ /tmp/dummy
dummy: unknown program `dummy'
Try '/tmp/dummy --help' for more information.

coreutils/coreutils@6b32a0bbd @pixelb Thankyou for the change.

[oech3]

busybox busybox is valid while uu-coreutils coreutils is invalid. @pixelb What should we do?
Also are you OK to accept the name *box as valid at GNU?

[sylvestre]

Ignore what busybox is doing

I'm OK to reject something like busybox busybox.
But, we still need to accept the binary name busybox to run our coreutils on busybox test suite.

[pixelb]

Before running the busybox testsuite, could you provide a "busybox" wrapper script in the path that uses env to set argv0 to uu_coreutils and call uu_coreutils?
That should be the functional equivalent.

#!/bin/sh
`dirname "$0"`/coreutils "$@"

on same path did not work with busybox test suite at least.

[Edit] Oh I did not env -a. I'll try it.

It might cause problem on AppArmor: #10135
