I have a few launch agent services which do some nice things for me, like starting pbcopy and pbpaste on network activity so I can copy and paste information across my ssh sessions without having to actually worry about the shell or terminal interpreting the data wrong. A huge plus is the :PBCopy function in vim works local and on remote servers to put the latest yank onto my system clipboard.
They should be tracked and installed on new mac machines along with the dotfiles.
