Moreover, the ACL semantics will (in general) be filesystem-specific.
Well, in the medium term I think the implementations will have to converge on a common authorisation model, or at least allow a grid like WLCG to have a common profile which gives the same behaviour at all sites. However, we seem to be quite a way from that at the moment, and the recent decision seems to be that we back off from that and approach it from a different angle.
The point isn't what you or I might think of as "correct" behaviour, just that different people (and different filesystems) will interpret these questions differently.
Err, yes - and if it is like that (as often seems to be the case in the grid world) it will be totally unusable in practice! (Cue another couple of years of Flavia's tests to get everything to have consistent behaviour ...) Stephen
