Remove the -v

Although this looks wrong and makes no sense in restorecon/setfiles.


	/*
	 * Do not relabel the file if the matching specification is
	 * <<none>> or the file is already labeled according to the
	 * specification.
	 */
	if ((strcmp(newcon, "<<none>>") == 0) ||
	    (context && (strcmp(context, newcon) == 0) && !force)) {
		freecon(context);
		goto out;
	}

The !force check should be removed.   It makes no send to relabel in the
case of the context being the same or the context being none.

Should be


	/*
	 * Do not relabel the file if the matching specification is
	 * <<none>> or the file is already labeled according to the
	 * specification.
	 */
	if ((strcmp(newcon, "<<none>>") == 0) ||
	    (context && (strcmp(context, newcon) == 0)) {
		freecon(context);
		goto out;
	}


I will provide a patch and update.
