* Stop specifying logbufs=8; that's the default
* Stop including nodiratime with noatime; the latter implies the former
Nothing wrong with being explicit, I suppose, but may as well keep the
mount options to what we can easily explain: we want noatime because
Swift does not use atime, so we don't want to lose any performance to
tracking atime.
