Here's a reroll of May's v1 [1]. Larger changes since v1: * Split into multiple patches, something like Karel had suggested [2]. * Punt to mount(2) for defaults for filesystem-independent kernel options, instead of adding local "(default)" marks. This is is also something like Karl had suggested in [2]. * Replaced the broken "synonym for auto" 'defaults' definition which I'd floated in v1 with a line from Karel's earlier suggestion [3]. * Added two examples to fstab(5) based on Karel's initial suggestions [4] and subsequent discussion. * Added a few copy-edit patches. After the v1 discussion, I think something should happen to (no)auto as well: On Tue, May 16, 2017 at 02:41:27PM +0200, Karel Zak wrote [2]: > On Fri, May 12, 2017 at 10:36:29AM -0700, W.

It's not clear to me whether Karel intends to clarify the mount(8) documentation on this point or if he intends to adjust the current libmount behavior, so I've left that language alone in this series. If the intention is to document 'auto' as another no-op (matching the current implementation), I'm happy to submit an additional patch.
