Except that if I do that, systemd stops working altogether - for example:

 [root@fomalhaut ~]# systemctl disable audit
 Failed to execute operation: Connection timed out

only reinstating the binary and re-starting journald fixes that.

systemd is the most passive-agressive utility I've ever seen.

So it's not possible to disable journald. Does anyone know any solution for that, 
which does not involve reinstalling a whole distro?

Thanks,
