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
although it probably would work with elasticsearch as well
as zinc is alleged to be ES-compatible
this is just the package and needs hooking into the service/log
infrastructure somehow
