Tell systemd to create, set, and ensure the right mode for the PID, configuration, and data directories. Only the exec bit is set for groups for the aforementioned directories. This is the least privilege perm that allows for the reading/writing/execing of files under the directory _if_ the files themselves give permission to its group to do so (e.g. when -sysperms is specified). Note that this does not allow for the listing of files under the directory.
