Hi, It seems we're now just reiterating what has previously been discussed *a lot*. IMO, highest prio is to resolve any issues related to YLbis. If we also need other clarifications to make the document easier to understand, that's fine. But I don't think we should fundamentally change the solution that the WG agreed upon. /martin Ladislav Lhotka <lhotka@nic.cz> wrote: > On Wed, 2018-02-07 at 11:41 +0000, Robert Wilton wrote: > > > > On 07/02/2018 10:29, Ladislav Lhotka wrote: > > > On Wed, 2018-02-07 at 11:14 +0100, Martin Bjorklund wrote: > > > > Juergen Schoenwaelder <j.schoenwaelder@jacobs-university.de> wrote: > > > > > On Tue, Feb 06, 2018 at 03:25:52PM +0000, Robert Wilton wrote: > > > > > > I think that the term "external" could also be confusing, since I > > > > > > think > > > > > > that > > > > > > sort of implies peer mount like semantics. > > > > > > > > > > The "inline" mount concept seems to subsume peer mounts.
