[OE-core] [RFC] Busybox: do not enable ENABLE_FEATURE_NON_POSIX_CP

[Andrea Adami]

Hi,

I was hit by a strange issue while benchmarking: I was copying some
large files to /dev/null and that was failing.
In fact, busybox cp foo /dev/null (and even cat foo > /dev/null) are
transforming the target in a regular file, with increasing size.At the
end devtmpfs was full...

After som eresearch I discovered that strange Busybox configuration option
ENABLE_FEATURE_NON_POSIX_CP.

Guess what? It is ENABLED in oe-core!

http://cgit.openembedded.org/openembedded-core/tree/meta/recipes-core/busybox/busybox/defconfig#n113

Now, do we really want it enabled by default?

Cheers

Andrea
