Browse Source 
files by systemd-journald

journald's journal-offline will relabel log files. It should be noted
however that this happens even if the files already have the correct
label.

avc:  granted  { relabelfrom } for  pid=11440 comm="journal-offline" name=".#system@97c1c6b7d7ed4333b671d09d9deee851-00000000003d4f26-0005f63f0972fd4c.journalb23e70204ab1737e" dev="dm-0" ino=418415 scontext=system_u:system_r:syslogd_t:s0 tcontext=system_u:object_r:systemd_journal_t:s0 tclass=file permissive=0
