	I would think anyone would want the acl behavior coherent across
the cluster.  Otherwise node 1 is setting an acl that node 2 promptly
ignores?  Yuk!  Especially since that admin could have accidentally
booted a non-ACL ocfs2 and not realize it?

	I don't know that it is valid.  But if we want to support it, we
can clearly differentiate between "my kernel doesn't support this" and
"I support it, but I was told noacl".
