Subject: [PATCH 7/9] refpolicy-minimum: systemd: fix for login & journal
service
1. fix for systemd services: login & journal wile using refpolicy-minimum and
systemd as init manager.
2. fix login duration after providing root password.
without these changes we are getting avc denails like these and below
systemd services failure:
audit[]: AVC avc: denied { write } for pid=422 comm="login" path="/run/
systemd/sessions/c1.ref" dev="tmpfs" ino=13455 scontext=system_u:system_r:
