 The context is a permission, it's like saying "when using -a try and
preserve the chmod/ownership/acl value, but if that fails just make a
new one up ... what could possibly go wrong!?".

 We differ from upstream by adding the -c behaviour to -a ... but unless
we want to turn SELinux off that's the right thing to do, IMO.
 The fact that this is another case of "SeLinux telling you in a really
weird way, that what you asked for is wrong" is annoying, but that
doesn't mean we should change what people asked for.
