it was only working by accident, when it worked, which was by no
means all of the time
note that we unconditionally perform the action (restart or whatever)
once we've started and got the initial state of the outputs. That's
because we have no idea whether the outputs changed in the interval
between the controlled service initially starting and watch-outputs
starting, so updates in that interval could be lost
There is nothing in this commit except for the changes made by
nix-shell -p nixfmt-rfc-style --run "nixfmt ."
If this has mucked up your open branches then sorry about that. You
can probably nixfmt them to match before merging
