Because we want the service to be started when the session starts. Otherwise we won't be able to pass the PAM secret if auto login is enabled to the daemon binary.
Currently, we used to fork/exec the daemon from pam module, pass it the secret through stdin, till oo7-daemon is started by systemd which would pass the dbus session bus env variable back to the main fork/exec oo7-daemon process so it can start the session. That ended up being a racy implementation. Instead, use a separate helper binary for fork/exec, make it store the secret and pass it to oo7-daemon once it is up and ready through a memfd passed via SCM_RIGHTS on a Unix socket.
