Dropbox was replacing symlinks with the target file or directory tree in synced copies. This obviously breaks legitimate symlinks since the whole point of having the symlink is to have a reference to the target, not another copy of the target.
It’s really simple: symlinks are symlinks and should be synced as symlinks. Now they are.
Uh, what?
Following symlinks is the default behavior for unix programs that requires extra effort to work around, why would it be "magic", or an antipattern?
