I searched the documentation for ‘alias’ and ‘symlink’ but not ‘symbolic’. My bad. I did not read the documentation cover-to-cover. I did spend half an hour Googling and reading forum posts / feature requests / bug reports where ‘symlink’ seemed to be the term of art. Perhaps add ‘symlink’ to that section of documentation?
I believe that I understand what is meant by “synced” here, but given the major players that bungle this, perhaps it would be helpful to spell out that symlink files are copied as-is like any other file, and that their suitability in the destination is the user’s responsibility. DropBox is the dumb gorilla in the room, and it’s also so convinced that what it does instead is right that it too is pithy in documenting it. If everyone got this right, you’d be fine being succinct. There is however a question leading reasonable people to be very suspicious of how any sync software handles this.
