The code tries to copy the security context from one file to another.
What happens here apparently is that a context is not present on the
"from" file and then it tries to remove the context from the "to" file,
so that it's also empty there. Perhaps we should be silent about this
failing. I suppose it happens because there is nothing to remove.
Hmm, no, there is a check for that.
