Subject: [PATCH 3/9] refpolicy-minimum: systemd:unconfined:lib: add systemd
services allow rules
systemd allow rules for systemd service file operations: start, stop, restart
& allow rule for unconfined systemd service.
without this change we are getting these errors:
:~# systemctl status selinux-init.service
Failed to get properties: Access denied
:~# systemctl stop selinux-init.service
Failed to stop selinux-init.service: Access denied
:~# systemctl restart selinux-init.service
