Excellent.  Thanks.  BTW We just received a patch from  Ondrej Oprala for
libselinux which according to him,

"I tested the patched libselinux with
$cp -a dir1 dir2
and got an approx. 20% save in instruction count. "

Basically the patch caches calls to setfscreatecon() and if the context is the
same as the previous call, it does a noop (Well it needs to do a strcmp) but
does not need to write to the /sys/fs/selinux file system.

Should make large cp's which maintain attributes, work a little faster.  Or
any other tools in coreutils that do lots of setfscreatecon calls.

rpm -q libselinux
libselinux-2.1.12-12.fc19.x86_64
