Fedora 27 workstation. I'm getting selinux AVC denial messages in the

label, the other files and the directory its in have
system_u:object_r:var_log_t:s0.
The AVC message of course go away if I relabel /var/log/journal but
then maybe two weeks later the problem starts happening again when the
log gets rotated. For whatever reason this is not happening with the
system.journal.

Is this a systemd or selinux-policy bug? Or other?
Michal, what you think about this?
How is the user-100.journal file created? It's end up as unlabeled_t so
some actions during early state of booting system?
Thanks,
Lukas.
