Motivation for this change

The new systemd in 19.09 gives an "Access Denied" error when doing systemctl daemon-reexec on an 19.03 system. The fix is to use the previous systemctl to signal the daemon to re-exec itself. This ensures that users don't have to reboot when upgrading from NixOS 19.03 to 19.09.

Things done
  • Tested using sandboxing (nix.useSandbox on NixOS, or option sandbox in nix.conf on non-NixOS)
  • Built on platform(s)
    • NixOS
    • macOS
    • other Linux distributions
  • Tested via one or more NixOS test(s) if existing and applicable for the change (look inside nixos/tests)
  • Tested compilation of all pkgs that depend on this change using nix-shell -p nix-review --run "nix-review wip"
  • Tested execution of all binary files (usually in ./result/bin/)
  • Determined the impact on package closure size (by running nix path-info -S before and after)
  • Ensured that relevant documentation is up to date
  • Fits CONTRIBUTING.md.
