This requires a further set of gofmt -s improvements to the
code, but nothing major. golangci-lint 1.45.2 brings golang 1.18
support which might be needed in the future.

Using MAINPID breaks systemd's exit detection, as it stops watching the
original pid, but is unable to watch the new pid as it is not a child
of systemd itself. The best we can do is just notify when execing the child
process.
We also need to consolidate forking into a sigle place so that we don't
end up with multiple levels of child processes if both redirecting log
output and reaping child processes.
