This change has not been merged and I see the relevant AVC on an Arch
Linux virtual machine (using systemd 239.370):
type=AVC msg=audit(1546723651.696:2091): avc: denied { read } for
pid=240 comm="systemd-journal" name="invocation:user@1000.service"
dev="tmpfs" ino=17614 scontext=system_u:system_r:syslogd_t
tcontext=system_u:object_r:init_var_run_t tclass=lnk_file permissive=0
type=AVC msg=audit(1546723651.799:2092): avc: denied { read } for
pid=240 comm="systemd-journal" name="invocation:dbus.service"
dev="tmpfs" ino=12542 scontext=system_u:system_r:syslogd_t
tcontext=system_u:object_r:init_var_run_t tclass=lnk_file permissive=0
What prevented init_read_unit_links(syslogd_t) from being added?
