This isn't really a Org question at all, but you all are smart and friendly people, and are likely to have run into this situation before. So I'm trying here before I turn to StackOverflow!
I have Org files in a git repo, synced across two Linux machines. At the same time, I have a few directories on these computers that I sync with colleagues, via Syncthing. One of these colleagues also uses Org, so instead of giving her access to my Org git repo, which would be a bit too much exposure, I hardlink some of the Org files into the Syncthing directories, and she accesses them there. With auto-revert-mode turned on, it's not too bad. Except that the hardlinks keep breaking! There are so many different systems interacting here that I have no idea where to even start looking. She's on a Mac, not Linux, and uses a fairly recent version of Emacs, plus Org from the ELPA package. She is *not* using git on her machine, just Syncthing and Emacs. I'm inclined to blame Syncthing, but I really don't know where to start debugging. If any of you have any relevant experience, or any advice about where to look, that would be much appreciated. Otherwise, please excuse the off-topic post... Thanks, Eric
