Yes, exactly! And generally for small changes that are more easily seen as diff. > https://9fans.topicbox.com/groups/9fans/T74b794a0b25b3452-M4e93273ae029a34387d5b847/9fans-persistent-cache-for-cfs > Thanks for the link! > I think for environments where the external source (fs) is heavily > used, inconsistency would become an issue. > Hum, you hit one point: if the diff doesn't apply there is some policy to decide about what to do, and there should be a way to administrate the thing by requiring user to reconciliate the two (and if the diff is already applied, the diff should be simply suppressed). > On Thu, Jan 23, 2025 at 3:10?AM <tlaro...@kergis.com> wrote: > > > > Does someone know of a "patcher file server" for Plan9?
