Thanks for the PR. Please create a separate branch for future PRs and avoid adding multiple different changes to the same PR branch.
Regarding the two changes:
g vs. group was obviously a typo.
I've added support for dynamic creation of the runtime directory to the systemd configuration template. Since I prefer to start the daemon as root (mainly due to additions in my private development branch), I've created a separate version of the configuration file for non-root startup.
Probably a typo.
